neocube
These geometric shapes are all made with neocubes, which, perversely, are not cubes but are spheres. They are small (5mm diameter) magnetic spheres made of neodymium. They are very strong magnets - notice how much weight can hang off one ball.
There are other photos on Flickr where I have the user name "Damocs"
