A Twitter bot that crawls Tumblr and Flickr for images, learning what tags and authors are good based on feedback on its tweets. Inspired by Archillect, but with a different aesthetic slant. The bot is the main attraction, but you can read more about how and why it came to be here.
@dupdupdraw is a Twitter bot that tries to make up programs to draw things on its own and also draws what you tweet at it. Look at the favorites for a quick Best Of, or read a quick intro or the more thorough README. All programs are valid, and the worst that can happen is you get a random solid color.
