Making a relativistic version of the classic arcade game asteroids was one of my personal benchmarks for AI models. Opus 5.5 ~one shoted this for me last night. This is pure AI slop, but it’s quite delightful and it does a great job rendering the physics of a relativistic asteroid field correctly. It really only works well on Desktop (mobile requires some jank buttons). But it is just webgl 2.0 so it ought to run on most up to date browsers.
