1. Twirling and Whirling: Viscous Dynamics of Rotating Elastic Filaments, movie of a viscously rotating elastic filament.
  2. Growing and Twisting: movie of a growing elastic filament loop with a preferred twist. As the filament grows, the twist is depleted by stretching which causes twisting stresses to build up. This leads to an instability that wraps the filament loop into a plectoneme.

  3. Growing and Twisting: same as above except that changes in the preferred twist lead to a T-type morphology.
