Movie S6.

First LC-PolScope, then tilted LC-PolScope time lapse of left-handed short rod rafts in an achiral background membrane of long rods shows the metastability of left-handed rafts. LCPolScope imaging indicates that all rafts have similar tilt magnitude at their edges which remains stable over time. Then, tilted LC-PolScope shows that the two rafts on the center-left side are lefthanded and thus counter-twisted. Scale bar is 2 μm.
