Iron Filings Sketch

The fluidity and optical flow in this inspiring little video sketch by Tom Wexler occurs with the interacting moire patterns as the spiraling rotation of illuminate lines creates waves of coincidental luminescence.

"Modeling a changing magnetic field and displaying it using simulated 'iron filings'. The calculation of the magnetic field is done on the GPU to keep things running quickly: this sketch runs at 30fps on my Mac. Depth-of-field effect added later in Final Cut."
