I can only speculate around what happened with the Pot video. I recall that there was some confirmation that it was recorded, but never saw the light of day. My only assumption was that it maybe didn't meet the quality standards Adam/Tool required, and hence never saw release.

The on a recent tour this happens:

To me, while it looks very Toolish, it actually seems more like a collection of ideas, rather than a more coherent video. My second guess at this point is that the existing video for the Pot was then reworked as a series of animations for use during the song live.

It'd be cool if Junior could give us some insight here (if he's allowed).
