Optical illusions

This is going to be my last post for a couple of weeks as I'm off to do some travelling. Optical Illusions & Visual Phenomena by Michael Back is an interesting website full of some really trippy optical illusions. Guaranteed to make your head spin in next to no time.


If you look around in the below figure you will notice the appearance and disappearance of black dots at the crossings.
