We had never heard of the Thatcher Effect before watching this video.

Basically, it states that our brains have the ability to process faces, even if something is a little off about it.

This video from Great Britain's The Open University via Gizmodo is a good demonstration of the Thatcher Effect, and it's also creepy at the same time.

Watch as this guy's eyes and mouth are flipped around, yet his face is still recognizable.

It'll creep you out a bit.
