This Is Not the Tholian Race Emblem. It is from a show called Space Above And Beyond. I saw it tonight being prominently displayed on a box during and episode of this show while at the hospital on TV.
Ergo I need the correct Tholian icon image. From the looks of this show, SOAB, it ran like 22 or so episodes on FOX back in the mid 90's before being canceled. From some screen shots I have seen of their DVD menu page, the same people who did Babylon 5 SFX, did the SFX for this show. In the back ground on the series DVD menu page is an image of Babylon 5.
I think had this show been given its due, it might have blossomed into something. But like Firefly, it was killed ala rumored one pissed off George Lucas.
Oh speaking of the high and mighty force master himself, I finally figured out where he came up with the wedge shape for the Stardestroyers. It came from a peace of pizza. While laying in bed eating cold pizza just a bit ago, I happened to look at the bottom of the slice of pizza I was about to eat and it occurred to me that it looked like the under side of a, yup you guessed it, stardestroyer.
Mystery solved.
