(And speaking of tagclouds)
Before I happened upon TagCrowd, I threw together a little quick description for Jenny of how one might generate a cloud given a list of terms and frequencies (since that's what we work with for CCCOA).
Fairly simple stuff, I suppose, but if anyone's interested in taking a look, here's a pdf of my tutorial for building a tagcloud by hand. The tagcloud isn't the tricky part so much as getting to the point where you have that list of terms. Once you do, a little size and color scheming, followed by a quick alphabetic sort, is all it takes.
