environmentally controlled randomized colored light projection dome
An analog pin is left ungrounded, and is therefore constantly affected by electrical signals passing through the air. This random signal is what controls luminosphere’s color changing durations and fades.
from the product description:
A mood-enhancing, tri-color, glowing light projection for dark spaces that exposes the beauty of additive color synthesis. Luminosphere provides ever-changing blends of red, green, and blue light that is projected vertically out of a translucent white dome. For anyone who is afraid of the dark, or perhaps simply in need of a mood enhancement for any room, Luminosphere provides an extremely
unique lighting alternative.
