We are not busting on the invention itself, as you have to respect the elegant complexity of this colored cube. But, let's talk about this thing as a Christmas gift. The kid loves the cube until, oh, about noon on Christmas Day, when the lazy little guy gives up, and the thing becomes a permanent fixture of foot injury on the living room floor.

We're not saying don't get this cube for that special kid in your life. We're just saying make sure that his nerd credentials are up to snuff or the cube will be consigned to a box in the basement along with the unsolved cube your parents bought for your dumb ass back in the day.
