I love lizards. Not as much as I love Tablet PCs, obviously, but they're bloody great, aren't they. Some of them can even climb up walls! This isn't a real gecko, obviously, but it's almost as cool - TIME Magazine certainly think so, as they've named it one of the best inventions of 2006. It has sticky pads on its feet so it can clamber around your floor, walls and ceiling to launch blitzkrieg attacks on you and your family.
