Experiments in Processing: eight-figure through a cube.
This is the famous eight-figure orbit in the three-body problem as described in http://emis.matem.unam.mx/journals/Annals/152_3/chencine.pdf.
This orbit, though unlikely, is astonishingly stable.
The integration is performed in Processing itself, with the leapfrog method (which is more stable for orbital mechanics).
