Supplementary Information

This file contains a video image of the particle motion around the cylinder at 2.03 K produced by an 11.2 kW/m2 steady heat current through the He II from below. This flux corresponds to a vortex line density of about 2.6 x 1010 m/m3 and an average line spacing of about 6.2 m. The particles are 1.7 m diameter polymer micro-spheres with a specific gravity of 1.1.
