World's Smallest Helicopter

I am not exactly sure if this IS the smallest, but has to be one of the smallest. Gadget Junction has a write-up on Picoo Z's new lightest and smallest Infra-red controlled helicopter in the world.

If you were wondering how big or rather small it is; it is only 17 centimeters long and weighs a cute 10 grams. Now you can use your palm for a heli-pad!
