it doesn't get in the way, i didn't even know about it for a long time. (actually on the contrary i think it helps me remember some things). a friend of mine was talking about it in an IM conversation and i realized i "see" a different colour for every letter and number. i don't actually see it, i just know it. at first i thought i was the type that saw colours for music, because i noticed once that i saw a different colour for certain songs. that was when i listened to CDs in a CD player (oldschool, haha). but i figured out it was the track number and not the music.

as for the picture, the 5's are orange to me and the 2's are yellow, but i don't think i could point out the triangle any faster than a non-synesthete. i think it's more obvious to some people with it.

and i doubt i could ever see what Daniel Tammet sees. it wouldn't come to me naturally anyway. i just see a colour, that's all.
