Whirling Twirling Propeller Trike
hankmt writes "A student at MIT has built a tricycle that applies force to a giant rear fan, instead of directly to the wheels. The effect...well, it's best to look for yourself, but it would be pretty useful on the post-apocalyptic roads of the Australian Outback. The blades of the trike even have built in LED lights which display colored patterns...and also warn pedestrians of their impending deaths."
The kid kills Megatron with the All-Spark cube at the end, rather than Optimus Prime committing suicide to save the Earth. The only good transformer to die is Jazz (the "black" transformer).
