Visually Representing Internet Data?
d0om asks: "I'm curious if there is a program that allows one to view a graphical, three-dimensional representation of data, much like in the Matrix concept in the book Neuromancer where you have a grid of different blocks of data, all presented visually. I'm curious if anyone can recommend anything of this sort to me."
I've taken SNMP data from radio network nodes, dropped it into Gnuplot, and placed on a web page a rotating GIF of a 3-D contour plot showing what the error rates are througout a building. There also are tools which can be interfaced to external data. I've used network configuration data to produce charts (although TkIned has tools to do this already).
Anyway, check out the brain, it might be close to what you're talking about (note: it's not open source/free software)
Check Rika Furuhata's page (in english ;)

There has been lots of work on information visualization. It's not really like The Matrix, but attempts to be. Check out PNL's visualization team's work. In Citeseer, look for articles about Bead and Lyberworld.
I've done some work on this with a system called Yavi; can send a reference if you want. It's not hard to find lots of work on this. For an historical bibliography (1993 + prior), see my references here.
