I'm using DLNA network in my home to show PC contents on TV that support DLNA. (Don't get confused, It's not like VGA or HDMI cable. TV gets files from PC and plays them, doesn't show screen of PC)

You know, it's boring to just listen music if there is no video. I want to visualize music, but my TV doesn't support it.

I'm looking for a way to generate this type (or this) type of videos from music files, or perhaps a source from which I can download ready made ones of popular music.

Anyone can help me?
