Naïs’ work on the collective dynamics of artificial microcilia [pdf]:

Click on the picture to watch a movie.

The cilia are self-assembled magnetic filaments. The distance between the cilia is 30 microns, the driving frequency is 2 Hz. The last frame of the movie shows the trajectories followed by the tip of the cilia.
