The periodic table is also fun (especially
if you are a chemistry geek).
In addition to the dynamic periodic tables
from last

Periodic Table of Haiku (alas, now missing from the web).
There is my college roommate's mnemonic for
periods 4-7.
And lastly,
there's Tom Lehrer's
song "The Elements" -- listen here. Here's
another
version
and
here
are the lyrics.
