About that I can say with reasonable confidence, that yes, it was a translucent hemisphere painted with 12 opaque "vanes" that spun , nested under an outer dome of "frosted" orange veering on "peach". At work I couldn't remember how many holiday bulbs were mounted upon the back plate.I'm very curious as well if you'll be able to replicate the effect within the gaming reality, complete with simulated mirror shards, Christmas lights and translucent domes.
Am I understanding the original model's effect correctly: the lights and shards didn't actually spin, but a painted dome inside an orange dome?
Both the Master Replicas prebuilt miniature (which I have) and the deluxe Polar Lights 350 scale assembly model replicate this feature rather closely, just using LEDs instead of incandescent bulbs. An slightly smaller dome with opaque vanes painted upon it spins via motor, the light from the LEDs filtering through it and the outer dome covering it. However, unlike the truly random nature of the holiday bulbs, the LEDs for both the MR model and Polar Lights kit are controlled by a circuit board.
