Created with our friends at remerinc., Getty Images "Gestalt" was an addictive online game featuring Rorschach-style inkblots (you know, those big black symmetrical blobs). Participants were asked to match an inkblot with a single image from a lineup of creative imagery. Each time they played, their name was entered into a drawing for a fantasy getaway.

The month-long promotion resulted in 270,000 site visits, and over 5,000 new customers for Getty Images. The promotion is over, but you can still play the game and put your psychology skills to the test.
