Just received this 15 minutes ago (3-8-2012; 1700) and I have to say it is just amazing. The thinness of the layers is nuts! yet it is really strong, although you will have to be careful. How on earth a mathematical expression can produce this object is beyond me. I would descibe it as a rectangular section cut out of a very intricate coral from a reef, but no coral was harmed in the making of it!! Fantastic piece, thank you Vertigopolka!
