I once had memorized the periodic table to 54 places (Xenon) by name, as a sequence with a few numeral fixed points. This helped me in High-school chemistry. Lost some chunks of the higher parts, but I have intuits about most anything in the periodic table. Some of this is visual memory.

I memorized that as a verbal thing initially, kinda like the alphabet song (which I know a large number of people still sing internally when they need to sort stuff lexicographically). But even the alphabet I have with sucess moved partially to visual memory.

IMO, visual memory is an underused resource to audiotorial thinkers (like myself) and probably vice versa.
