I bought a couple of galaxy lights for the living room and bedroom.
The stars (green lasers) remain stationary, while the other colorful shapes rotate at various speeds. They can also be set to remain stationary. The light also features a music mode, which causes the lights to flash in beat with whatever music is playing. It uses a sound sensor to listen for the beat, so there's no need to connect my device to it, wireless or otherwise. This galaxy light is only $10 (USD) at Wal-Mart.
@Miram It helps a lot, because when I'm in a dark room, it looks like people and things are moving around. I think it's caused by floaters in my eyes. It can get old pretty quick.
