A lab of small 3D experiments.

First-person view from a low-orbit space station — procedural continents, drifting clouds, city lights, and a glowing atmospheric limb.

The Sun and nine planets with real axial tilts, Kepler-paced orbits, and Saturn's Cassini-divided rings.

A four-armed spiral galaxy with 70k stars, a bulge, a halo, and live differential rotation — all in one shader.

Gravitational lensing of a Schwarzschild black hole with a hot accretion disk.

A traversable throat with an alive interior — flowing star streaks and chromatic walls of warped spacetime.

A point-mass gravitational lens warps a background source into a glowing ring — magnification spikes on the caustic.

Volumetric ray-march through a clumpy cloud lit by a young hot star — Hα red, OIII teal, and reflection blue.

Core collapse, ionising flash, expanding shock, and slowly fading remnant — a 16-second loop of stellar death.

An eccentric-orbit comet shedding two physically distinct tails: fast blue ions, slow curving dust.

Tens of thousands of old stars packed into a Plummer-profile sphere — Population II yellows, the rare blue straggler.

A neutron star with magnetic poles tilted from its rotation axis — twin beams sweep the sky like a lighthouse.

An orange giant and a blue dwarf circling their barycentre — viewed nearly edge-on so they take turns eclipsing.

A young star ringed by Keplerian dust, with five dark gaps carved by forming planets — a stylised HL Tau.

A Large Hadron Collider event display — concentric detector layers, repeating proton–proton collisions, helical charged tracks, and calorimeter energy deposits.
