What Is It? Game 124

Don your Mad Scientist lab coat, folks … it’s time for this week’s collaboration with the What is it? Blog. Can you guess what the strange contraption above is?
Contest rules are simple: place your guess in the comment section below. One guess per comment, please. You can enter as many guesses as you’d like. You have until the answer is revealed at the What is it? Blog (duh!)
Prizes: free Neatorama Mad Scientists T-shirts to the first person who guessed correctly, and to three submitters of the funniest albeit incorrect guesses.
For more clues, check out the the What is it? Blog. Good luck!
Update 1/25/10 – the answer is: A rotary spark-gap transmitter that would have been part of an amateur radio station back in the 1920s. Congratulations to Russell who got it right first (but submitted many guesses in one comment. I’ll let it slide this time, buddy!) and to Mikhael J who got it exactly right. Three additional winners: mci209 (Tweety’s Worst Nightmare), Jenn the Hen (My Little Frankenstein Monster Maker kit) and Lactose the Intolerant for the effort
