Illusion Lab #06 — Shape experiments

Try illusions where shapes, brightness and color appear without being drawn, by changing how the figure lines up. In Experiment 1 you can also turn the circles and match the angle where the triangle just appears. This is not an eyesight test, and records stay on this device.

Can you see a triangle?

There are only three cut circles. No triangle lines or fill are drawn. How does it look as you turn the circles?

People see these differently. Not seeing them is perfectly normal.
