That crystal prism thingy thing...

[sorcerer999]

I know it's been discussed on this forum years ago around the time of IYD, but I wanted to ask what is the technical name for that device featured in the "Sorcerer" video and in the "In Your Dreams" documentary. It's a small music box looking thing with crystals attached that, when rotated and set in the path of sunlight, casts prisms against a wall. Any info on the name and/or where to purchase is greatly appreciated. Thanks in advance!
