Tutorial on Mouse Hack to Trackball

[isugoat]

Someone posted 1 or 2 weeks ago in a thread about trackballs and they mentioned a link to a site that had a thorough tutorial on hooking a happs trackball to a hacked microsoft mouse.  for the life of me I can't find it again, I searched the forums, then manually searched them, then googled and still can't come up with it.
so if ya know any good sites with mouse hack trackball tutorials please post em here and hopefully one of em will be the one i'm lookin for...=/
