The BlissLight Starfield Projector is a light box that projects out a laser-powered moving starfield. (Shop projectors here.)

You can swivel the unit to aim at a wall or ceiling and even add a nebula cloud effect at the twist of a knob!

It's very easy to use - just plug it in and enjoy. 

Post Update 6-12-12: Sorry, but the BlissLights mentioned above are no longer available. Check out our collection of novelty accent lamps for more of this type of lighting
