How It Works

THE PROCESS

-

1 OBSERVE IMAGE

When presented with the image, your eyes will quickly scan it, relaying the visual informatio­n to the brain.

2 ANALYSE SECTIONS

The brain then chooses which section and shapes to focus on. This choice will determine how you perceive the image.

3 PROCESS SHAPE

Your memory stores shapes the brain has encountere­d. It compares these with the shapes analysed to find objects in the image.

4 PRODUCE PICTURE

Objects and shapes are pieced together to create your initial version of the double image.

5 QUICK RESULT

We are quick to make our first judgement of the illusion, as fast interpreta­tion of visual informatio­n helps humans survive.
