musicplasma : the music visual search engine

Just when I think that there isn't anything on the net anymore that can impress me, I come across something like this! Musicplasma bills itself as "the music visual search engine." It's cool. Type in the name of a musician, hit search, and you'll be given a chart that shows what other artists or bands are in the musician's musical orbit. What a clever way to discover some new music. And what a cool way to visually represent ideas.
