slowly have i realized that i am blessed with a perceptual experience with interesting symptoms and no side effects. several years ago i noticed that, while i watched basketball through a window, my mind was creating noises to accompany the bouncing of the ball that i saw. at some point, i learned the word for this. i think it was when one of my sister's described how numbers have color, for her.

What i learned today is that the word synesthesia describes the class of conditions, of which my visual-aural and my sister's number-color experiences are distinct types. My favorite encyclopedia describes the latter as "Grapheme-color synesthesia" but doesn't have such a fancy name for my variant. That encyclopedia has interesting links at the end.
The bouncing ball will test whether you have my variant. I experience it a lot while using computers, because there are often visual events with no sound, either in the user interface or in banner-ads on web pages. Another instance is watching the turn-signal of the car in front of me at a stop light.

It's a pretty neat condition. And since it "runs strongly in families", i'm curious to know whether my other relatives have variants. feel free to post a comment or email me (even if you're not a relative...). Maybe at the next family reunion, we can have a volleyball match between the dyslexics and the synesthetes.
