one question, can dean design an anti gravity device? if he can, well, all's good, but if he can't...
seriously though, take a segway, add a few more gyrochips (so you can have 6 degrees of movement [up, down, back, forward, left, right]), and then throw on an anti gravity device. nice, easy, and a perfect holiday gift!
heck, next year we can make flying robots! we can make robots that play Quidditch!!
i need to get out more...
