The TVs in my house are usually on, typically with the sound turned off (I love closed captioning!) as light, movement, and noise background.

I really love "ambient" videos--my favorites are the Hawaiian Dreams series--an endless loop of waves, waterfalls, etc.

I also bought one called, "Sanctuary" which is a fish one, but the new age music bugs the hell out of me.

When I was at the Hirshorn museum, I bought an art video called The Way Things Go--an elaborate "domino"-style experiment in motion, which is also pretty cool.

I'm tempted to buy a fireplace one.
