The more I look at it, the more I am going, "Yep. That's a roulette wheel."

The funny thing is, the design of the Discovery is a rejected model for the new Enterprise from Star Trek Phase 2 (which became Star Trek The Motion Picture). It's almost identical.

And yes, it looks a lot like a roulette wheel.

Just saw and image of the underside of the ship.

Still not convinced it isn't a roulette wheel

And the lighting reminds me of Vegas. Which isn't helping its case.
