I had a chance to see this new invention at the New York Toy Fair and it is finally public on their website.
There is a small disk which levitates a few inches above the surface of an illuminated base. The disk rotates on its own. You can place up to 4 ounces of whatever you like on the disk and it will endlessly hover and rotate while the lights from the base illuminate it.
If you have any kind of collection (action figures, minerals, shells, glass figures, etc), this is really killer.
Hopefully they'll post some movies soon. It should be available from retailers by Christmas (that is what they promised).
