If there is a gizmo I really crave to take control of, this is the one. As The NeoCube (Strong Force Inc.) website puts it,
The NeoCube is an entertainment device like no other in the world. Composed of 216 individual high-energy (whatever that means) rare-earth magnets, the NeoCube allows you to create and recreate an outrageous number of shapes and patterns... The NeoCube Alpha is perfect for gaming, expression, stress relief, dual hemispherical brain stimulation and much more.
The rare earth metal in question is neodymium, which, according to Wikipedia, is not that rare at all. Which is a good news for all of us needing affordable dual-hemisphere brain stimulation.
