I had this idea to get my friends together to create art. I created a simple tool which allowed them to draw on a small canvas. I gave them a small number of pixels each, but they could cooperate (and earn bonus pixels) or overwrite others' work.
I ran a small iteration of this project back in 2009 with my friends. People had fun so I decided to add a few new features. Currently, the tool has an ability to "mine" tokens directly on the page - with enough patience, you can earn free pixels just by staying on the page. I'm also trying to make it a little easier to draw and explore what others have done.
I hope to be done in a couple of weeks, at which point I'll give all my classmates a chance to contribute with a relatively large number of pixels each. In the meantime, you can play with the test run, by mining the pixels (you can also email me to get a token). The canvas so far is shown below. Click through to contribute!
This is the result of the 2009 iteration of the project.
