Here you can fly a spaceship around a Schwarzschild black hole (and, if you like, try to catch an orbiting satellite without falling into the horizon), from the point of view of an external observer.
The same thing, but now from the point of view of the infalling spaceship, giving you the chance to cross the horizon.
Here you can watch the 2d Ising model struggle towards equilibrium, and you can adjust the temperature by yelling at it through your microphone.
Draw a self-gravitating structure, start it spinning, and see if you can keep it from collapsing or flying off to infinity.
This is a collaboration with art collective Plataforma UMA. Make a stylized version of a black hole and watch it evaporate, set to a soundtrack by Jonathan Uliel Saldanha.
