Perception Lab
Your eyes don't see the world. Your brain interprets it.
Every experiment here is interactive - guess first, then watch the reveal. And in some of them, your own eyes do the rendering.
- Colour
Same Colour?
Two squares. Are they the same colour, or completely different?
- Size
Which Is Bigger?
Two orange circles. Tap the bigger one.
- Perspective
Which Line Is Longer?
A classic - but you still won't see them as equal.
- Attention
The Vanishing Colours
Stare at the dot and watch the colours cease to exist.
