A short twoperson dance, with a twist. Or more accurately, a shear: time is remapped so that there is a delay that increases as you move from the top of the frame down to the bottom. Or in math: (x’, y’, t’) = (x, y, t – y), in some units. Via Terence Tao and Alex Fink.

Can I shamelessly plug my own variation of this, which doesn’t map the delay in time by the yaxis, but by lightintensity?
Sadly, it’s crappy cam footage of a live installation.
