This is the Hot House twist on those famous cat's eye marbles we used to all love as kids - except this one is about 682,000 times better than the machine made variety, WOOHOOO!! Each vane of the marble has two different colors fused together, with sparkly dichro between each vane, and all together it is stunningly gorgeous! Go here if you'd like to see a video of a similar marble spinning for the camera, showing how nice it is: http://www.youtube.com/watch?v=XOe1QLY8Bl4
