Utah Computer Science Professor Ronald Resch. Interesting <a href="http://www.vegreville.com./tp2.html">egg factoids can be found here</a>--including that it swivels like a weather vane. Vegreville has an <a href="http://www.vegrevillefestival.com/">annual festival</a>. More <a href="http://www.geocities.com/wenjin92014/pysanka/VEGR.htm">images of egg here</a>. The Vegreville Pysanka was the first physical structure completely designed with computer-aided geometric modeling software. <em></em>There is a good <a href="http://www.geocities.com/williamwchow/egg/e-egg.htm">description here of the complex geometry involved</a>. It's based on a <a href="http://www.ics.uci.edu/~eppstein/junkyard/resch.pdf">technique </a>(PDF) he developed and <a href="http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/search-bool.html&r=18&f=G&l=50&co1=AND&d=ptxt&s1=4397902&s2=resch&OS=4397902+AND+resch&RS=4397902+AND+resch">patented </a>for folding a flat material (i.e. sheet metal) into flexible surfaces.
