NEW! Glass and Geometry "All my stained glass work is based on geometry. Yes, it is math I am talking about! The following lines are a short explanation of the shapes I work with and a bit of theory around them. " (C) Hans Schepker 2003 - This site is worth checking out, Mr. Schepker has created glass sculptures, glasslamps, ... based on math and geometry- all glass.
