Week Four - Ghost Galaxy

On my last trip to Disneyland, I brought my girlfriend to the new Ghost Galaxy version of Space Mountain, which she had never seen before. While waiting in the line for about an hour, I got some shots of the effects they display on the "mountain." I looked around and noticed at least one light projector, but I don't know how many it takes to create these changing effects, it's really interesting. I've also been trying to figure out how it works, in terms of our color theory. So the moutain is normally light, which means that in white light (sunlight), it reflects all colors, so that it appears white. That would mean that if we projected a green or red light was projected onto it, since white contains all colors, it would reflect back that green or red light, making the projected area appear green or red. So, with the areas that look like blue infecting the green, either there are different projections creating those specific shapes, or they are creating blue on top of green, which is beyond my comprehension right now. Either way, it looks creepy and cool, and Disney knows its stuff.
