OK, forget MyFreeCar and Autowraps. Soon you can wear advertising on your clothes. Impressions are registered by infrared heat sensors. Sign me up for “special deals on Britney Spears merchandise if fans wear the pop star’s videos on their clothes.” Woo hoo. (I’m kidding! Really.) Seriously, though, this makes me think of the wonderful possibilities for high-tech “kick me” signs when these come out. If it’s on someone’s back and he can’t see it, boy is that a hacker’s dream come true. (btw, apparently Carvertising has run out of gas.)
