Mmhmm- sounds like it, although I can't say for sure. Interestingly enough, it's not a psychiatric or nurological condition, rather a genetic trait. My cousin has it, but her letters and numbers have personalities as well.
I also see my months of the year and days in a week in an oval pattern, like a gameboard.
Try http://en.wikipedia.org/wiki/synesthesia for more information. I found out what it was called when I told my mom at 7 "I didn't know you could make a red letter (P) into a purple letter (R) but just adding an extra line, that's cool" and she got me evaluated before they suspected Aspergers- the pediatrician said it wasn't a disorder, rather, a congenital personailty trait; no mental delay is evident with synesthetes, but heightened IQ could also occur from it as well.
