This illusion will make your walls go wobbly
This illusion will make your walls go wobbly

Here's a little something we in the trade call an "eye frazzler". Actually we don't. No one says that. But they really should! Let's see if we can make it happen.

Stare at this for about 30 seconds, then look away to a different bit of your screen or a nearby wall.

Nuts, isn't it?!!

This is the "waterfall illusion" named by Robert Adam, who first observed the effect after a trip to a waterfall near Loch Ness. Scientists think they know why it happens. When you're watching a waterfall, or the strobe illusion above, the brain cells that detect motion in one direction become tired.

When your eyes look away, the cells that detect motion in the other direction get more active to make up for the worn-out ones, and static objects really seem like they're moving.

What do you think? Are you feeeeeeling veeeeeeery sleeeeepy? Well, it is Monday morning.
