Falling interacting softbody rectangles @animations

Improved softbody renderer. Surprisingly computer intensive simulation - approx 10 hours per minute video. This since every rectangle interact with every other via possibly intermediate rectangles.

Visuals in Python and FFmpeg.

2^28 balls constrained by gravity and a W

$Fractal emerging from chaos in a circle Shown is a ball bouncing in a circle under gravity for many start positions. The sixth bounce is associated with a color of the circle for colouring a pixel representing the start position. For a relatively high pixel density, the resulting image becomes a fractal. In the very end, a corresponding image for 10 bounces is shown, indicating, unsurprisingly, a more chaotic behaviour. Music by @gpcbass! The song is called Cayenne.$
