M.C. Escher

Making GeoGebra tools in Geometry.  Some reminded me of M. C. Escher's work.  Took time to look at some of his pieces.    Used   http://www.photovisi.com/collage/create?template=template8 to do the collage of M. C. Escher.

Repeated designs where made by constructing a geometric shape, making it a tool, and then using the tool many times to create a design.  Collage was again created using photovisi.
