I spent about 45 minutes playing around with the visuals and reading the information. I found it helpful as well as interesting to understand the brains ability to percieve and understand different visuals, and the way it does. It would be a good lab exercise I feel for the students to read this and do the interactions. It presents concepts that are easily confused and makes them easy to understand in an effective manor.
I feel that this site could be used by just about anybody interested in this topic.
