Ji Lee's book Word as Image.
Started 20 years ago as an assignment in his typography class at art school.
"When we were children, letters were like fun toys," he says. "We played with them through our building blocks. We colored them in books. We danced and sang along with TV puppets while learning C was for 'cookie.' Soon, letters turned into words. Words turned into sentences. Sentences turned into thoughts. And along the way, we stopped playing with them and stopped marveling at A through Z.
