Why is all the cool stuff in Japan? Check out the Flip-Flap urban flower. Just like a regular flower the Flip Flap needs sun in order to function - the twist is though, that it needs the sun to power the included solar battery. What this boils down to is that there is no need to change batteries or recharge them for the life of the plant. And of course, since it is plastic, it requires no water. Oh, and before we forget to mention, the flower dances by moving its leaves.
