Visual Audio
 

I am looking for software which would make any song visible with graphics like what you see in the background of concerts when they are not showing pictures of the band themselves. 60's psychedelia, or other media which changes with music, like you get with a light show, but would like to project this on an LCD monitor. You could use this with iTunes when you don't have an attached video. Anyone have something they have come across?

The sound spectrum site looks promising. I'll take a few of the free downloads and post a reply once I try them. Thank you very much.

Do you know if G-Force works well with a MacBook? I'm not seeing much on the G-Force website regarding Apple products.
