I still can’t do the original Rubik’s Cube after watching a couple of YouTube instructional videos. Technically, these are called VCUBES but still retain all of the original’s fun. I’m thinking that these would make a great stocking stuffer for the math major in your family with prices starting at $35. Check the video after the break of a dude solving one of the 7×7x7 in a competition. Insane.
