A Sierpinski Gasket (or Triangle) is a type of fractal named after the Polish mathematician Waclaw Sierpinski who described some of its interesting properties in 1916. It is a nice example of how an orderly structure can be created as a result of random, chaotic behavior. In fact, the gasket can only be created by random behavior. http://serendip.brynmawr.edu/playground/sierpinski.html is a good site to learn more about Sierpinski Gaskets.
