An animation created to accompany a workshop during the BRIDGES 2012 conference. The workshop centers on making a physical model of a (36)D (36)L chiral tessellation transformation. The animation centers on a mathematical model of the transformation of a (36)D (36)L Chiral Tessellation where the center of rotation and translation for a chiral sets of triangles is located around the center of a six set tessellation for one segment and a 12 set tessellation in another segment of the film. A chiral set is rotated about its common triangle center of each set. The two centers stay in common with each other throughout a full 360 deg. rotation of the respective triangle sharing the common center. One triangle in the set is rotated clockwise and the other counterclockwise. The vertex of the clockwise rotation triangle is connected to an adjacent counterclockwise rotation triangle. A vertex connection is not allowed to be broken.
