A little help here.

I was stumbled across an online application - I think it was Flash based - that was this amazingly vast network of bands and artists.

The thing about it that was awesome is that each band or artist was graphically displayed in this network as circles of varying size and color. The size I think was related to how much music the band has produced and color, perhaps genre, I don't quite remember.

Anyway, what I mean by network is that all of these circles were connected. They were connected based on similarity of genre and sound - so the closer a circle was to another, the more similar they were.

You could type in the name of a band, and the application would jump to that bands circle. Then you can observe the web of connected bands around it and see what sounds similar.

An amazing way to discover new music if you ask me.

But yea, I never bookmarked it, unfortunately. I was hoping someone would have an idea of what I am talking about, and maybe has seen it, and could help me find it again.
