I remember seeing a link tracking API in Java from around here that this reminded me of. Really is a cool interface this has. Gonna have to swing by the alternative search engine forums to get up to speed. Thanks for the nudge in a better direction.
Hey, no problem. KarTOO is amazing flash. Had to play with the interface again after reading your post...that graphic they generate is way too cool not to use once in a while -> even if you aren't looking for anything at all. :)
