Soapless washing machine by Sanyo. Works by using ultrasound to remove dirt from clothes, then electrolysis to remove dirt from the water to prevent it from settling back on clothes. The electrolysis part only works in Japanese water with that model, due to the particular chemicals that Japan uses. Should see if they have introduced a model for the U.S. That would be keen.
Secret Art of Chip Graffiti by Harry Goldstein. Fun article on finding small pictures (a few hundred microns big for instance) on popular microchips. Including such things as Dilbert drawings and the Florida State Seminole logo. Built out of the circuits themselves. Pretty nifty.
