Add this to your list of pretty useless-but-amusing USB gadgets – the USB-powered Desktop Bouncer. Whenever you’re away from your computer and do not want any prying eyes to go near it, hook up the USB Bouncer and watch him tick off people who come too close to your workspace, thanks to the integrated motion sensor circuit within. He can spew up to half a dozen phrases, and I have a hunch none of them are too polite to begin with. I don’t know about you, but his facial features reminds me of the dumb-but-tough albino mouse in the animated feature Flushed Away where the only things missing are the ears and the tail. The USB Bouncer is available for $19 a pop.
