Movie S1.

Flow of LCM_X1 between micropillars in real time. One of the cover glasses was patterned with epoxy pillar arrays (D =10 µm, P = 20 µm, H = 9 µm) coated with silica to impose homeotropic anchoring on all boundaries. The temperature was kept at 90 °C. The flow was manually created by mechanically pressing the LC sample with tweezers.
