OK, time for your next illusion!
This picture is "animated"; it is actually two pictures that switch back and forth continuously. One of the pictures is a monochrome (black and white) photograph of a rock feature in the desert. The other picture is the same photograph, overlaid with an unusual color scheme.
Here's what you do:
Wait until the weird-color photo comes on again, and then concentrate on the black dot in the center. Continue concentrating on that black dot for the entire time the image is shown. You'll find that when the image changes, the "black and white" photograph actually looks like an ordinary, full-color photograph for a few moments - that is, until you move your eyes.
