I Photoshopped up a lid and the side, but never got as far as getting the wrap around part to the right shape to fit a pot - I'll see if I can dig up the file. I'd LOVE a tub of "The Stuff" to be made nicely (i.e. not just paper glued on plastic, but actually printed on plastic).
I remember that someone also made a bust of one character when The Stuff poured out of his stretched-out mouth - that was cool!
