Earlier this year at the CES show, a company called ION Audio caused a stir with their Wall-Mounted Turntable, above. They have some other unusual product offerings skirting that line between "neat" and SkyMall catalog:
ION's dual-lens Twin Video Camera shoots both forwards and backwards simultaneously, letting an interviewer record themself and the subject simultaneously. It's a nifty idea, though it maxes out at a disappointing 640x480 resolution.
Their Water Rocker is a floating speaker that lets you stream audio from an iPod (located in a dock on dry land) or your TV out to the swimming pool.
The Mobile DJ Speaker is like a carry-on for partymakers, featuring a telescoping handle, wheels, an integrated amp and speaker, dual iPod docks and an internal battery good for 12 hours of runtime.
