eBay of the day: Anorectal Transducer. Yes, it's what you're thinking. Yes, it's used.

Noooooooooo! eBay item 380050845372 is a B&K Type 1850 Anorectal ultrasound transducer. Yes, you put it there, connect it to an ultrasound machine, and it produces awesome 3D images. The auction contains the unforgettable lines: "Comes in nice wood box. Came from working environment." Noooooooooo!³² I'm assuming that one of you dear readers has $2,499 to drop on this, and plans to connect it to Max/MSP and create the most terrifying musical instrument in history... (Thanks, Paul)
