This video goes into a little more depth (heh) on perceptual organization and depth cues.


If you can't get the floating finger sausage to work, do you have an astigmatism? Sometimes having an astigmatism, especially if uncorrected when you were young, can throw off some of depth perception. This is also why some people are unable to do the Magic Eye posters.



For the kitty spotters, Izzy was in the cube behind me for most of filming but never in frame, so she is featured in the credits. I woke her up to do so, which is why she looks a bit sleepy while playing.
