An interactive simulator of plant nutation
Currently available at http://unred.org/nutation
This simulator has been realized with Unity 3D for the upcoming paper "The Kinematics of Plant Nutation Reveals a Simple Relation Between Curvature and the Orientation of Differential Growth." by Renaud Bastien and Yasmine Meroz in Plos Computational Biology https://arxiv.org/abs/1603.00459
