A short two-person 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.
Just got the book today. It will be my Thanksgiving reading while working on my presentation for the national math convention.
Another great example, Muse’s music video for Unintended:

Thanks Sean – enjoyed watching this.
And another one is Midnight Juggernauts’ Vital Signs
Can I shamelessly plug my own variation of this, which doesn’t map the delay in time by the y-axis, but by light-intensity?
Sadly, it’s crappy cam footage of a live installation.
