An interesting Website with an interesting ranking and relationship system

Liveplasma: music, movies This site is a really interesting visual creation. It is basically a music and movie database but the way the data is displayed visually is very interesting. The halo around the band or movie you have entered indicated it’s popularity and then genres of music that are related in someway are linked. You can zoom in and out and it also displays a discography or details of the director’s movies. An interesting approach that encourages serendipidity. I think this is probably an ontology based creation as it seems to require more that just a simple hierachicial structure to create it. What do you think?;-)
