I was doing some research on tracking and I came across this awesome bit of kit in a presentation by Necros (http://www.youtube.com/watch?v=E_CCpg5VQ4k - well worth the watch, it's pretty much a tutorial for Buzz)

Has anyone used it before?
I've been using it for about a week and you can get some great results from it!
