What color should i paint my room?
Answers:    Many theatrical suppliers approaching ROSCO sell gobos (patterns that shape light). And they vend lighting instuments that the gobos fit in and move it for the effect of river. There must be a company that sells a similar product to be precise more appropriate for residential use.
There are also table lamps that enjoy moving shades that create a moving pattern on the wall. I focus they're called panoramic lights?
I hope this at lowest gets you closer to an answer.
