Demos
These programs are written in cint and run in the browser. Each one comes with its source, the C that cintc emits from it and the receipt of its run.
A Double Pendulum Swinging in 3D
Three double pendulums a millionth of a radian apart drift away from each other, and a tether pulls them back or pushes them apart.
Three Bodies, There and Back
Three bodies under gravity part from their twins a millionth of a unit away; a tether pulls them back, and a reversed run returns to its start bit for bit.
Avalanche in a Rocking Box
A 3D dam break of 1,024 water particles parts from twins one position unit away; a tether pulls them back, and any particle order gives the same bits.
Gravitational Wave Chirp in 1024 Bits
A 3.5PN compact binary inspiral evaluates relativistic phasing down to ISCO in 1024-bit integers; a tether pulls twins into phase lock, followed by ringdown.
Turn-based and lockstep games also have their own index at /games/.
