Movie 1. The vorticity field generated by recoil locomotion of a finite body is shown. By periodic variations in presented surface area, in conjunction with recoil forcing from the oscillations of an internal mass, the body advances with each period to the right. Here, the Reynolds number based on the frequency of oscillation is 16.
