WHAT'S NEXT: Finish reading the group of books purchased about Synesthesia. (Tasting the Universe: People Who See Colors in Words and Rainbows in Symphonies by Maureen Seaberg and The Hidden Sense: Synesthesia in Art and Science by Cretien Van Van Campen. )
And hopefully it will start to spark how this can result in a visual experience for my thesis.
