In this case, nerd is particularly accurate (see the Paper Nerd post below about local paper workshops): That’s because Robert J. Lang is a former physicist and engineer-turned-artist. His innovative approach to the traditional art of origami has earned him a reputation as one of the world’s most important origami artists. I came across this YouTube video via the Indianopolis Museum of Art website; the IMA has an exhibition of Lang’s work that includes some of his monumental paper sculptures.
