This is a link to a Flash animation of Tom Lehrer's song, "The Elements"--which, of course, was done to the tune of Gilbert & Sullivan's "I Am the Very Model of a Modern Major General."
My friend sent this to me some time ago, and I just got around to opening it. Nicely done, I think. I wonder what he'd do with The Formulary Song. (Note that there's a line missing in the DT version.)

By the way, if you check the fine print at the bottom of the page, there's a link to an interesting Australian interview with Tom Lehrer.

Aloha,
