Name That Weird Invention!

It's time for the Name That Weird Invention! contest. Steven M. Johnson comes up with all sorts of crazy ideas in his Museum of Possibilities posts. What should we name this one? The commenters suggesting the funniest and wittiest names will win a free T-shirt from the NeatoShop. Get creative and leave an entry in the comments.

Contest rules: one entry per comment, though you can enter as many as you like. Please make a selection of the T-shirt you want (may we suggest the Science T-shirt, Funny T-shirt, and Artist-designed T-shirt categories?) alongside your entry. If you don't select a shirt, then you forfeit the prize. Good luck!

Update: The first-place name selected was Yawn-mower, from kfd90. Second place went to chaise-lawn from Norris. Neither winner selected a t-shirt, which hints that maybe you guys enjoy playing these games with or without a prize!
