This image tells you nothing about the fascinating Neocube. Essentially the balls are magnetized and it can be reconfigured countless ways to make cool shapes and forms. Check out the video on the site. NOT RECOMMENDED FOR SMALL CHILDREN.
The NeoCube is great. As a puzzle, it doesn't get old quickly since you have to get acclimated to dealing with the polarity. It can also be desk art or refrigerator magnets and it makes a great clacking sound, like never ending bubble wrap.
