I am sure there are some of those out there! I saw a guy online who had color and shape based synesthesia with letters and numbers and he had built is own alphabet from that and actively used it for note-taking. He seemed exceptionally intelligent and his notes were a complete trip to look at. Some people called him schizophrenic in the comments because they didn’t understand it, but it was very clear to see that there was a logic and a system to his alphabet and his notes that wouldn’t have been there if he had schizophrenia. People fear what they don’t understand xD

I wish I could remember where I saw that. It was awhile ago. It was so cool.

From what I have been able to tell, many people with synesthesia are either artists or scientists. I’m sure there are also bankers and accountants with this affliction out there, but I guess you don’t hear about them as much as they don’t tend to become famous.
