Check the animation video made by Maya Hartmeier during her graduation project at the ZHdK (Zurich University of Arts) to explain our work on chameleon colour change.
Maya built some cool animations to explain how chameleons play with the light interference phenomenon to shift colour through the active tuning of a lattice of guanine nanocrystals within dermal iridophores.
