Taste the Rocket
James Wannerton tastes words. Due to an rare neurological condition he's had since birth, all spoken and written language is translated into phantom tastes and textures in his mouth. Many of them nice, plenty of them horrible.
Last year, Wannerton made a map of the London Underground, swapping out the names of stations for descriptions of the tastes that appeared in his mouth. That same year he rode the Toronto subway, too. This is what the TTC tastes like.
