"Being, just being. Feeling my sight clouded by these eyes, my hearing muffled by these ears, and my thoughts, my bright, airy thoughts trapped in the labyrinth of coiled fat."
-from August Strindberg: A Dream Play. (...he looks like Johnny Depp?!)
To ask "what is it like to see through eyes, hear through ears, and think through a brain?" invites the question "Is there any other way?". We "see" and think it is reality. Optical illusions allow us to "hack" our own retina (or visual cortex)- and expose its mechanisms. Check out "mindhacks"... both book and blog and incredible optical illusions from Prof Michael Bach.
