The following are creations by Rinus Roelofs. His study of math merged with art has created some fascinating sculptures and images. Check out his site for an amazing array of each.
From his site: "Rinus Roelofs was born in 1954. After studying Applied mathematics at the Technical University of Enschede, he took a degree from the Enschede Art Academy with a specialization in sculpture. His commissions come largely from municipalities, institutions and companies in the Netherlands, but his work has been exhibited further a field, including in Rome as part of the Escher Centennial celebrations in 1998."
I was pointed to this mathematical illusion by Pardalote Flits. This illusion presents something you know to be false in a simple visual way that might confuse your senses.
Here is another illusion. I have seen it presented as a puzzle or math problem but commonsense tells us that this must be an illusion. The only thing we have to do is try and explain the illusion.

Here is an illusion of a different type.
I was talking to a friend of mine that has taken up coin collecting rather late in life. He figures it will be cheaper then getting married again. Anyways he went into a coin dealer he knows to talk shop and came across an interesting tidbit.
According to his coin dealer 1972 pennies are significantly more valuable than 1932 pennies.
Now I know that I am a layman and know absolutely nothing about this hobby but this doesn't seem right to me. Can any of you explain to me why this might be?

Well, it's because
1,972 pennies is worth $19.72
But
1,932 pennies are only worth $19.32
This is another example how we bring our own preconceptions into everything we do. Here many of us saw the image of the penny and the date on the penny and automatically assumed that we were talking about the years 1972 and 1932.
