Very weird picture trick

[Kev]

All I see is my ceiling, is this because I drank some beer earlier?

It must be. If you stare at the red dot and focus soley on it for 30 seconds then look up and start blinking you will see an image of Beyonce floating above you.

I guess it works by showing you the inverted image, and whilst focusing on the red dot your eyes somehow flip it back to the way it should be or something.

It's very clever and it really does work just like those magic eye pictures from the 90's.
