Now here's an idea whose time has come -- vaccum shoes. Electrolux has created this rather frumpy but functional pair. Just slip 'em on and wander aimlessly around the house like you do already. You could have a pair for guests when they come over; have them earn their dinner!

Sadly, this is just a sucking concept right now. Apparently the vaccum king hasn't worked out some pesky details, such as where to store the dirt or how to monitor the power. May I just suggest that they make these in any other color but puke green?
