This is probably a "plasma disk" as seen in Star Trek Borg
episodes. Pretty expensive to be considered a toy! They do
run on flyback type transformers and are very similar to a
plasma ball except in disk form. There is a webpage, out there
somewhere, about them and the company that makes them.
I would like to make one too, so if anyone has any ideas how
please post them!
