'Do me eyes deceive me earsight? Is it some dreams?' Artemus Ward 1834 - 1867

Everyone is aware, I'm sure, that things are not always as they seem. I am particularly fascinated by the visual anomalies that are more commonly called Optical Illusions. Some of the best-known - and one or two unusual ones - are extensively explored at Illusionworks; there is a collection here; have a look at Vision3d; and try the miscellany of all things visual at Grand-Illusions.

Here, with the aid of Microsoft GIF Animator, I have tried to demonstrate some Optical Effects that interest me. Please wait while the animations load. Enjoy!

	AFTER EFFECTS	Look at the moving patterns - and see the strange effects
	CUBE	Classic 'which way is it facing' cube and rod animation
	ERASER	Eraser on - or above - a table
