Toy maker Uncle Milton has introduced Force Trainer, a game that utilizes NeuroSky's brainwave-controlled gaming technology. In a manner similar to the Mindflex we got our heads on at CES, the young Jedi dons a wireless headset that communicates with a simplified EEG. If you focus well enough, the "training sphere" rises in a 10-inch tube. Seems pretty harmless, no? At least until your humble child starts lifting rocks and choking people by simply furrowing their brow and gesturing menacingly. If you find this an acceptable risk (or you feel the need to work on your own mental prowess) the thing should be available this fall for just under $100.
