Can handle multiple light but for the demo I have only one so that I can FAKE the illusion that the light emits an orb/circle of light. That is just a costume. The Engine is the shadows on cast behind the 4 objects. The objects also light up when the lights get closer but that part isn't mathematically accurate. (Off by default)
I did this on a whim. Not meant to be perfect but I found this to be pretty cool if you are ok with some mathematical inaccuracy and lack of colored lighting.
