What Is It? Game 150

It's been a while since we played the What Is It? Game - so let's get crackin' with this one: Can you guess what the strange object above is for?

Place your guess in the comment section. One guess per comment, please, though you can enter as many as you'd like. Let others play, so do not include any web links or URLs. Two winners as usual: the first person
who guessed correctly and the funniest albeit wrong guess will win T-shirts of their choice from the NeatoShop.

Important: Please write your T-shirt selection alongside your guess, or you forfeit the prize, mmkay? (May we suggest the Science T-Shirt, Funny T-Shirt and Artist-Designed T-Shirt categories?) You have until the answer is revealed at the What Is It? Blog.

For more clues, check out the What Is It? Blog. Good luck!

Update 9/18/10 - the answer is: A Fulton traffic light finder, some of the old cars had low roofs that made it difficult to see a traffic light if the vehicle was too close to it, this device was invented so that the driver could hold it near the windshield and see the light through it, patent number 2,526,045.

Mike Morris got it right first, but didn't choose a T-shirt. Congratulations to Samantha B. who first guessed the Sailor Moon wand.
