Our weekly What is It? game, in collaboration of the What is It? blog is this strange tool: guess what it is and win a free Neatorama T-Shirt (I think I'll one t-shirt contest a month from now on, till my supplies run out).
Game rules: place your guess on the comment section below but post no URL links (let others play, please!). Past winners can play, but won't win anymore T-shirts, ok?
While you're at it, definitely check out the What is It? blog for more fun stuff!
Update 1/12/07: It's a corn sheller (patent 99106). Congrats to withvous for the correct answer!
