Circa 2000 I interviewed for a three-letter-acronym agency that shall remain unnamed and they were interested in me working on a 3D visualization interface of traffic across a network which actually sounded pretty fascinating. Sort of like "packet filter plus visualization" after given physical location information about the computers in question; even without that information, though, it would use something like the graphviz algorithm (or one of its options) to lay out the map on a 2D plane in 3D. Different kinds of traffic was color-coded, you could zoom in and inspect any stream, roll forward or backwards in history, etc.

  We have no names, man, no names. We are nameless. Can I score a fry? Thanks.
