(CBS) - Focus your eyes on the white dot and prepare to have your mind blown. This clip is called "Silencing awareness of change by background motion" and it was recently named the best illusion of the year by the Neural Correlate Society. Those colored circles don't change color the whole time, or do they?
This illusion comes from two Harvard brainiacs, Jordan Suchow and George Alvarez. For some reason, the spinning motion of the colored dots suppresses the viewer's ability to notice the changing colors, making them appear solid while moving. In reality, the dots are changing at a constant rate the whole time.
