Anthony Mattox Interaction Design + Digital Art

My department at MICA recently changed it’s name from Interactive Media to Interaction Design & Art (IxDA). Interactive media was perhaps an appropriately ambiguous name considering the work coming out of the department, but the new name is hopefully more self-explanatory.

To advertise the new name there is a t-shirt design competition, and then free shirts for all the majors. I’ve been working on some designs, mostly just typographic logos. This one looked half decent and I combined it with something I was working on in Processing. Here are a couple sketches.

One of my recent assignments in one of my classes was to develop a card game. Not surpisingly, this wasn’t an easy task. The game was to be for two or more players and had to involve a deck of cards and one other object.

I didn’t come up with a good name for the game I came up with, but I think it’s half decent, especially given a week to create it.

To play the game you’ll need a deck of cards and a set of tokens for each player. The tokens are used to mark which player controls a card. These could be poker chips, beads, coins, or anything else. You may need up to 25 per player.

Give it a try and let me know how it is or if any of the rules are confusing.

Setup:

25 cards are placed in a five by five grid from a shuffled deck of playing cards, each player is dealt four cards, and the rest of the deck is placed face down. Each player picks a color of game pieces

Goal:

Players compete to control more cards than their opponents by the end of the game.

Rules:

• Players take turns and try to control as much of the grid as possible.
• Each turn a player has three options.
  • Switch two adjacent cards on the board, vertically or horizontally.
  • Replace a card in the grid with one from their hand. The initial card is placed in a discard pile or left underneath the new card. The player picks up a card from the deck to keep four cards in their hand.
  • Pick up a new card from the deck and discard one from their hand.

  

• If a player makes a set of three or more cards in a row they place their pieces onto those cards. A set includes cards of the same number or consecutive cards of any suit.
  
  
• After a card has been claimed by a player it is frozen and can not be moved or replaced except by a higher card which completes a set.
• If someone replaces a card in a set with a higher number card, creating their own set, the rest of the initial set still belongs to the player who created it, but the replaced card is now controlled by the other player.
• If a card within a set is included in another players set that card is claimed by that player regardless of the sets value.
• If a player extends a set (e.g. from three to four cards) the whole set belongs that player.
• When there are no more cards in the deck, each player takes one additional turn and the game ends.
• The player with the most cards claimed at the end of the game wins.

I also made a graphic (full-size image) of the better part of the game with some brief explanations. It might make things a little clearer.

This semester I’m taking my first formal class in typography. I’ve gleaned enough to do a decent job with it, but it’s definitely something I should do. So far the work for the class has involved a series of exercises, each producing a number of square compositions exploring letter forms and their interrelationships. In each we had a number of restrictions and goals. Here are just a few that I found more interesting.

Of course, after playing with letters in Illustrator for a while, I thought it would be a good idea to throw some letters in Processing. Processing handles text pretty well and the results can be exported as a PDF (vector graphics). The text will be rendered as text in the PDF. For scripts involving words I created an SVG file of the word so I could have more control over the type.

The next three used my particle system with a perlin noise flow field as in some of my other projects. Each characters’ mass is based on its size, but one character is also a little lighter than the other making them separate slightly as they are pushed by various forces. The noise field is also slightly offset in a third dimension to cause further separation.

Using a more recent iteration of my particle system I created these next two by replacing the springs with the word interconnection.

I used a cellular automata script to create this last one. Each state of a position in the array corresponds to a letter in the word automation which is also written out in the first generation of the system. With so many states the system becomes to complex to form any recognizable patterns, but I thought it was at least a little humorous.

This sketch builds off one of my recent experimentations in wave motion. In the script an array of waves is created by various inputs. Each wave effects the array of ‘fluid’ and creates a rippling structure. Here the structure is rendered not just after all the waves have been calculated but after each wave is processed.

The result is a stack of rippling points flowing between each other. I first just rendered each wave as a thin bar, to make sure everything was working properly, and then added a color property to the wave class. I dropped the symmetry to avoid some unintended interpretations. The script runs much slower, as I should have expected. I’ll try and streamline things a little (although it’s already very simple) and put it onto my interactive site. I might just have to put some limits on it so people don’t crash their.

Now a bunch of pictures!

Back at the old particle system I’ve been enhancing the interaction. In the applet you can now easily create and remove particles and links. Particles can be dragged and multiple particles can be selected. Right now everything is controlled with keypresses, but I plan to build an interface to easily switch between tools and to modify particle and spring properties as well as environmental properties. When its a little closer to finished I’ll post it into my interactive site.

In these images, springs are drawn in purple and forces are drawn as blue lines, stronger forces are darker. Drawing the forces is a little unnecessary but it creates interesting patterns. Which is, at this point, all this application really does.

What is particularly interesting is the way structures move. In the image below, a radial structure is dragged by its central point. The whole mass distorts into a cardioid shape. It eventually collapses into chaotic motion. Moving any particle in an interconnected set creates waves through the rest of the system.

Interested in pushing the interactivity of my Processing work a little further I decided to create a little piece which responds in a more interesting way to mouse movements.

The sketch has an array of vertical bars across the screen. When the mouse is moved (or clicked) waves are created that move along the array and bounce off the walls. The speed, direction, and distance of the mouse motion effect the pool differently simply because of the way the set of waves created overlap.

Slow movements create small ripples, moving your mouse along with a wave makes it grow, and moving the mouse around quickly creates complex noise. The waves still don’t bounce off the edges perfectly, but it usually works pretty well.

A second version of the script creates waves with a different shape, but is otherwise similar. In the first version, the waves were shaped to replicate water ripples and the overall area of the bars stays about the same. In this second version, the waves form large bulges. The wave shape creates a different texture and motion and changes the interaction.

I began programming about a year ago, primarily working a language called Processing. Much of the programming I have been doing has be to create generative or algorithmic artwork. Such works involve writing a script to dynamically generate images based on a variety of systems and inputs. One of the thoughts behind this type of work is that a piece is not manifested as a single image, but in a method which creates an image. What is important is style, texture, motion, and the relationships between elements and colors. The particular composition is generated dynamically each time the piece is viewed. For the past year I’ve been documenting most of this work as still images in this site, a trail of my development, but not a full representation of the work.

www.anthonymattox.com/interactive is a little site I’ve made to display my interactive works in one place. Take some time to explore the projects. I’ll keep adding more work as I create it as well as a number of other projects that still need to be cleaned up and put into the site.

Enjoy!

Most of the projects in it are created with processing and your browser will have to have the java plugin installed to run them. To run the 3d applets you will have to click trust in the dialogue box that appears. There still might be some bugs in the site so let me know if you have any issues.

Once again, It was time for a complete re-design of my website.

After a few frustrating iterations, my previous design was just something created to be as simple as possible so I didn’t screw anything up. White background, black text, lots of pictures. It worked out pretty well, but it didn’t exactly sell me as a web designer (to be fair this one isn’t very web-designer-ish either). It was also a little cold and unfriendly. It also had some formal issues, such as wide text columns.

This new site fixes these issues, and is also generally more visually interesting.

The Blog layout stayed more or less the same. The post meta-data is in the left column followed by the main column for the post content. A third column, on the right hand side, can be used to annotate images and other elements within a post. I’ve also added a fancy tag cloud and page numbers thanks to a nifty plugin. I’ve been struggling between having a wide column with nice big images, and a thinner, easier to read, column, with smaller images. To try and get the best of both, I added Thickbox (sorry Lokesh, I was already using jQuery).

I feel my work is much more effective when it is larger and I had to sacrifice larger images in my blog for the sake of the layout. Thickbox helped this some, but just to make sure, I added the option to add a custom background to every blog post and page. Someone with a larger screen looking at on of my projects will see an elegant column of images, but will also have it filling in the background around the page. To enhance this I also have custom highlight colors to match the background image. Any page that shows multiple posts pulls these custom options from the top post.

The Home Page has grown substantially. A work from my portfolio is still featured at the top and it’s background pulled. I’ve also added more links to other parts of my site and around the web, and a silly picture of me, just for fun.

My Portfolio now has three viewing modes (large images, excerpts, and thumbnails) and benefited from other site wide additions.

As of right now I still have some little tweaks to make, but everything seems to be pretty much in place. I hope to get some feedback from everyone on the new page look. Comment below, or try my fancy new contact form.

In my blog I frequently share code for little projects in Processing & Arduino. It’s always bothered me to look at the black and white text which, in comparison to the beautifully colored code in various editors, is quite a strain to read. I considered a few ways to do this, primarily client side with JavaScript, server side with PHP, or something pre-formatted in any language.

I decided to write a script to add in the necessary HTML to color the code, which I could then paste into my site. Although this does add a fair amount more to the size of the HTML files on the site I decided it was the best way to go. A server side script, probably built into a WordPress Plugin, would be nice and easy to use, but it would be run every time the page was loaded and would be a load on the server. A JavaScript highlighter would also work well, but it would still be a large script anyway and it would add the hassle of browser inconsistencies and run time on slower browsers.

Since I was building this script I wanted to make it available to others. The Processing and Arduino communities, which the script is built for, are both great about sharing code, and this will make sharing just a little bit easier.

The script is built into a simple site at www.anthonymattox.com/code_formatter. You can paste your code into the page, adjust the settings, and format it. The script returns the HTML and a chunk of CSS based on the styles you selected on the first page. Paste the HTML into your site and either add the given CSS or use it as a model to write your own.

In my blog its styled to look something like this. Unfortunately it’s still black in rss readers.
