A small conveyor belt in the crack in the couch would run into a box whenever it senses pressure on it. It should know what's on it according to the weight. Perhaps it could announce whether it's just picked up change, the remote, a tissue, or an unknown object. Coin roller optional.-- fogfreak, May 16 2003 Oh man I was hoping for a conveyor belt to bring me everything I possibly need to the couch for infinite laziness.-- calculust, May 16 2003 Oh, great. A voice from the crack.-- lintkeeper2, May 16 2003 I seem to remember a peristaltic/self cleaning couch idea, but can't find it.-- phoenix, May 17 2003 Doubles as a treadmill. The couch potato has no excuse.-- oatcake, May 18 2003 Fabulous! One of my least favorite chores, digging for gold in the sofa crevices. I turn up lots of change though.-- dentworth, Jun 19 2004 halfbakery
