Figure 2.

The calculated curvature (a) and torsion (b) as a function of time for the example trajectory shown in figure 1(b) from a bead moving in an 80 μm chamber. (b) Open shading denotes times during which the trajectory torsion is positive and thus moving with a right-handed component. Gray shading denotes left-handed sections. Note that the torsion crosses zero multiple times and thus the bead trajectory is not predominantly right or left handed.
