Eric Brunning (@deeplycloudy) returns to talk about doing science in the field in this crossover episode with the Embedded Podcast! 

Eric on Embedded: 268: Cakepan Interferometry

Eric on our show: 134: Launching Balloons out of a UHaul.

The paper was Reconstructing David Huffman’s Legacy in Curved-Crease Folding by Erik D. Demaine, Martin L. Demaine and Duks Koschitz. Elecia is working her way through Erik Demaine’s Phd thesis on the same topic as well as Jun Mitani’s excellent book Curved-Folding Origami Design. Geology also has folds.

For 3D printed origami, Eric mentioned Henny Seggerman’s twitter @henryseg.
