Here's an interesting story of a girl in Michigan with Grapheme-Color Synesthesia. In other words, she visualizes each digit, zero through nine, as a different color.

For her, and others with the same condition, it adds a new splash to math work.
Researchers in Alberta are using mathematics to predict driving patterns in order to understand the science of traffic jams. Their studies are helping to understand how the actions of one driver can amplify as a wave of behavior on a busy road. The behavior, researchers say, is similar to wave patterns caused by detonation explosions. A greater understanding of these patterns can help city planners to set safe speed limits and create a smoother commute for hundreds of thousands of people.
"It should be evident that each step in my career has rested on a firm foundation in mathematics. For me, the study of mathematics was the key that opened the doors to the universe."
