Galaxy: a 3D cosmic music visualizer in the browser

Twenty-seven 3D scenes — a gravitationally lensed black hole, a volumetric nebula, a supernova, a spectrum sea, an infinite cathedral — rendered live with HDR bloom, streaks and grain, free.

Open Galaxy 3D Or BLOOB (2D)

Who this is for

Artists who want cinematic release visuals
Planetarium-style ambient screens
Anyone who loves space

Ray-marched, not sprites

The black hole bends every ray around the horizon so the accretion disk wraps into an Einstein ring; the nebula is a real volume the camera flies past; the supernova detonates on drops.

Cinematic pipeline

HDR rendering, UnrealBloom, anamorphic streaks, diffraction glints, god rays, film grain and a palette-aware grade — driven by the music.

Branding and export

Logo, album art, titles and lyrics; MP4/WebM at 720p–4K; phone remote and MIDI for live use.
