The UNIX equivalent would probably be Xtraceroute, a beautiful OpenGL traceroute utility that shows a globe with your traceroute path on it. I've only ever seen it running on an UltraSPARC and it's about as sexy as network software is ever likely to get: according to the homepage it has also been successfully compiled on GNU/Linux, FreeBSD and SGI.
