I saw this video on Visual Thinking and had to post it. Kermit was ahead of his time (1959).
Temple Grandin, of course, is the leading world expert on autism and visual thinking. Below is just a short interview about visual thinking, but if you are really interested in her and her work, a simple Google search will reveal more videos, and some of her writing. She is brilliant and "to the point".
I really like her perspectives on education.
