Some technical details: The backend runs on Google App Engine. The server keeps a concept of the 'freshest' canvas. I have a cron job that aggregates all pixel changes and creates a fresh canvas. When you download the app, you initially download the fresh canvas. After that, you only download a very small amount of JSON which represents the pixel changes.

Yea, that's where I got the idea from. I wanted to improve it though. His system had people sending him entire images, and you had to go through him to pay.

In this app, you can control it pixel by pixel through in-app purchases, and you get 1,000 for free so you can actually participate without paying.
