Forget the Picoo Z's, no matter how much fun they are they can't be as cool as making and flying your own indoor remote-control 'copter. And over at this site there's a set of instructions that'll help you DIY, assuming you have some spare CD drive motors and servos lying around, and are happy with soldering and detailed rotor-carving. The instructions even say how to add a wireless cam beneath the fuselage... useful for, um, imaging the precise moment you crash it into your cat? I suspect more nefarious purposes. Still, it's a full cyclic-control aircraft, so it should be extremely flyable. [Heliproject via Hacknmod]
