It's "Six Degrees of Kevin Bacon'' on a much larger scale. I've been playing with it for awhile, and I must say.. it is fucking weird.
I just connected Slayer's - Reign in Blood cd with Martha Stweart's Cookbook - Pies and tarts, and it only took 12 hops.
I'm not real sure how it works, I bet it just a bunch of bullshit thrown in to make it look like fun, but it is entertaining at best.. and It seems to be associated with amazon.com, as you can buy all the shit that it uses to connect your starting and ending items. You can do music, movies or books.. I'm not sure about tv shows as of now, but give it a whirl!
