Team In Digestion ate up the top honors at Seattle Startup Weekend.

Kyle Kesterson made a name for himself as the creative force behind Giant Thinkwell, the Seattle celebrity gaming startup whose mascot is a lovable squid. But Kesterson, who left Giant Thinkwell last month, now appears to have tapeworms on the brain (or the intestine for that matter).

The artist and designer emerged tonight as the winner of Seattle’s most recent Startup Weekend, pitching a concept called In Digestion. In the game — being developed for Kinect, Android and iOS — game players assume the character of Marvin the Tapeworm.

The goal? Attempt to jump and duck in an effort to eat as much food (pizza, cupcakes, etc.) as one can muster as the items move across the screen.

Sounds nasty, huh? Well, it gets even better, since legendary rapper Sir Mix-A-Lot (who just came out with his own Baby Got Back app) provides some of the voice over work. You can check out some of the early screen shots of the game at the company’s Web site, EwAwesome.com.

In Digestion was one of 18 teams to emerge at Seattle Startup Weekend, the intense 54-hour coding marathon hosted at the headquarters of F5 Networks. (Interestingly, as you may recall, Kesterson’s previous company, Giant Thinkwell, actually was the product of a past Startup Weekend).

In addition to In Digestion, other winning projects included Kick the Bucket, Tapin.tv, Drinks on Me and Weatherful.
