You know, before I turned this thing on-edge, nobody even mentioned Spock's Jellyfish. I think the supposed similarity mostly comes down to the vertical disc motif. The Jellyfish isn't even a disc, really; it's a flattened mushroom cap with a spinning ring behind it and a tuning fork tail.
I don't really care one way or the other, especially since the basic design of the Polaris
far predates the latest Trek film, and this version is actually closer to that original design, other than the vertical orientation, than anything else I've done since. If you think the design is too close to the Jellyfish, take it up with Ryan Church.
