residue is a new collaboration with choreographer Lydia Hance and composer Robert McClure.

This video demonstrates experimentation with simulated fluid dynamics and optical flow, using the dancer's movements as the 'energy' source.

In addition to the fluid dynamics, this video includes my implementation of a 'smearing' effect, in which certain parts of the image (selected in advance) remain smudged on screen even after the fluid simulation has resolved.
