Gestalt, Gestalt! Where for art thou, Gestalt?

Let's go on a treasure hunt. This week, we're searching for optical illusions associated with perceptual groupings.

• horizontal and vertical symmetry
• radial symmetry 
• figure versus foreground 
• similarity 
• proximity 
• continuation 
• closure 
• common fate

Gestalt theory holds that we oversimplify complex images...letting context influence what we see.
