What is Twipestry?
Twipestry searches for tweets, and then produces a patchwork of images which are associated with keywords in those tweets.
The images are taken from Google's image search. The backend uses a modified version of Mark Kolich's TwitterCacher.
When first loaded, the images are taken from the public timeline. To see the twipestry for a particular user, enter their username in the box above and click the blue arrow. When a twipestry has been created, clicking on an image will take you to a twitter search showing the tweets with that keyword.
