Swarovski crystal optical lens, a computer programmed motor and a white LED. As you can see in the video down below, the white metal armatures rise in syncopation by rotating cam before gravity releases them earthward, which then activates the LED to move closer to the crystal lens. Through the magic of diffraction, you end up with a rainbow effect being flung to the floor, creating a perfect environment for... let's say, a rave. Or, you know, your next bedroom.
