Giant Easter Egg
April 8, 2004 2:40 PM Subscribe
This giant Ukrainian Easter Egg (pysanka) was built in 1975 in Vegreville, Canada by (then) Univ. Utah Computer Science Professor Ronald Resch. Interesting egg factoids can be found here--including that it swivels like a weather vane. Vegreville has an annual festival. More images of egg here. The Vegreville Pysanka was the first physical structure completely designed with computer-aided geometric modeling software. There is a good description here of the complex geometry involved. It's based on a technique (PDF) he developed and patented for folding a flat material (i.e. sheet metal) into flexible surfaces. Ronald Resch has had an interesting career.
