No, the cubes aren't moving. 😵‍💫😵‍💫

But what is causing the illusion?

they are moving I put a straight edge on them

The lines don't move. Place the mouse pointer over any of them and you'll see.

My brain screams for mercy! Such a strong illusion.

I hate but love it at the same time 🫨

But what is causing the illusion?

…light effect; considerong as white=lightness, black=darkness

One of the best illusions I've ever seen

Too cool.

Loved this !!
