Are you tired of Ugly Christmas Sweaters which seem impersonal?
Mariko Kosaka, champion textile engineering and a million other awesome things, has released a fun doodad (technical term) for generating ugly sweaters from your favorite photos.
Ok so it doesn’t actually generate a pattern you can knit, but it’s fun to play with.
By the way if you aren’t already familiar with Mariko Kosaka’s work you should be. She’s got a great presentation on how textiles have led to the development of the Web at large.
