Fields and forces you can poke — ripples and interference, orbits and chaos — each one solved in real time so the rules reveal themselves as you play.
Real-time 2D Navier-Stokes solved entirely on the GPU — paint vorticity with your cursor and watch ink swirl and dissipate at 60 fps.
A WebAssembly-powered 2D wave laboratory — run interference, diffraction, refraction and reflection experiments in real time.
A real-time, geodesic-traced binary black-hole merger — light bends around two event horizons as they spiral in, chirp and ring down. WebGPU only.
The chaos of gravitational three-body motion, integrated in real time.
