OPTICAL ILLUSIONS

I know, it’s not exactly an experiment, but illusions are still cool. Designing illusions is even more fun! Use these prompts, found in multiple places online, to drive a conversation and eventual design of optical illusions!

Illusions are images that use your EYES to confuse your BRAIN

Take a look at this grid:

Did you notice the small grayish dots between the black boxes. They are not part of the drawing – they were put there by your brain! Scientists call this “visual vibration.” Basically it means that when you see patterns of black and white, your eye sometimes confuses the two and blends them into patterns of gray that you see here. You are seeing something that is not really there!

The repeated patterns and lines trick your brain into thinking that there is movement as it tries to make sense of the image. Pretty cool, huh?

Look at the dot and then move your head towards the screen and away from it.

Screenshot 2016-04-18 20.51.40Look at the dots in the center. Which one is bigger? Like many similar illusions, the dots are the same size…really! It can be hard to tell because your eye uses the other dots to make a comparison.

Check out the spiral…except it is not a spiral, just circles.

Don’t believe me? Use your finger to follow the fake spiral.

Screenshot 2016-04-18 20.52.16Hey, this is weird. Click on the image to make it bigger. It looks as though it’s moving, but it’s not. The shapes confuse the eye (really the brain) into believing that they are moving.
