I love these things.  Not only do they simply blow my mind, but I find them so useful when trying to explain why an injured brain may not understand the visual world.  So much of what we know is perception, so much of perception is assumption, so much of assumption is unquestioned. 

What we see is not really what's out there. 

Doubt rules.  :oD
