If you find yourself in a disagreement with a friend or co-worker you can either settle it using a grownup approach like polite discussion, or with a set of these awesome RC Battletanks. Controlled via an accompanying Android or iOS app they can turn any neutral cubicle into a militarized zone in no time.
While you won't exactly be able to fight battles with it, you'll still have plenty of fun with the Desk Pets TankBot. It's a cute $20 toy which can be fully controlled by any iOS gadget.
SKITTERBOT claims to be the fastest legged micro-robotic toy in the world. And from the video, which shows a swarm of these colorful $20 robo-cockroaches zipping around in a frenzy, I can imagine that might be correct.
