Daniel Tammet, a writer and artist with high-functioning autism and savant syndrome, defines synesthesia as “an unusual cross-talk between the senses.” A synesthete himself, he perceives language, numbers, and colors as intertwined. “Words can have colors and emotions; numbers [can have] shapes and personalities,” and thus “the world is richer, vaster than it too often seems to be,” he said in a TED Talk called “Different Ways of Knowing.”
