None of these really look like what you described but I’ll post them in case you haven’t seen them:
Sega Toys Homestar Planetarium Space Theater Planetarium
Create a Night Sky
Discovery Ultimate Star Planetarium
ThinkGeek Laser Stars Projector
More like this?
It doesn’t move, but the idea is right. Pricey, too.
I should say that I really appreciate all this help. Looking back at my replies, it looked like I was getting a bit uppity. I apologize if I came across as a bit harsh.
