Super Greg was a concept web site idea for Lee Jeans.. they did 3 of them.. The original 3 aren't up anymore I don't think but there are a lot of mirror sites and tribute sites still up. I can't remember the 3rd one off of the top of my head but here are 2 that I know of:
Super Greg
Curry/Rubberburner make sure to check out Tiger!
And here is a good link to the
origin of all of this
if I can find the 3rd one I'll post it
