Don’t believe what your eyes tell you.
Stare at the black cross and see blank space transform into a green dot.
Thank you, Troxler effect.
Move your eyes above this line and the black and white dots will look like they're rotating clockwise.
But focus on the central red or yellow dots and the outer ones reverse to show their true direction – counter-clockwise.
Keep looking at the flashing green dot and the yellow ones will disappear.
That'll be the Troxler effect again. Explanation here.
Fix your eyes on this black dot and the grey stripe will turn blue.
