Title      : Escher For Real: on the synergy between science and art
Abstract   :
The art work of M.C. Escher needs no introduction. We have all learned to
appreciate the impossibilities that this master of illusion's artwork
presents to the layman's eye. Nevertheless, it may come as a surprise for
some, but many of the so-called 'impossible' drawings of M. C. Escher can be
realized as actual physical, tangible, three-dimensional objects. These
objects will resemble the Escher's drawings when viewed from a certain
viewing direction.
In this talk, I will discuss and present some intriguing three-dimensional
so-called "impossible models", following drawings and art-work made by
Escher and others, which were designed using a variety of geometric modeling
and computer graphics tools.  We will present some of the fundamental
concepts that allow one to create these tangible artifacts and conclude by
portraying a modeling package to synthesize many of these so called
"impossible models".
