BLOOB

A black hole that bends light to your music

Galaxy’s Black Hole is ray-marched with gravitational lensing: the accretion disk’s brightness by angle is your spectrum, the inner disk flares on the kick, ripples cross it on snares and jets fire on drops.

Who this is for

How the lensing works

Each pixel’s ray is bent toward the singularity every step, so light from the far side of the disk wraps over and under the horizon into the Einstein ring, and the photon sphere glows at the edge.

Doppler and redshift

The approaching side of the disk beams brighter and bluer; the inner edge dims with gravitational redshift.

Music mapping

Disk brightness by angle = the 64-band spectrum; mass breathes with the sub; kick = inner flare; snare = ripple; drop = bipolar jets.

How to do it

  1. Open Galaxy — it runs in the browser on WebGL
  2. Choose a song or play the demo
  3. Pick a cosmic scene and add your logo or title
  4. Record, or export an MP4 at 1080p–4K

Questions people ask about black hole music visualizer

Does it run on a laptop?

Yes — the scene renders at a reduced internal resolution on lower tiers and upsamples.

Is the physics real?

It is a Newtonian approximation of the geodesics, tuned to look right, not a GR solver.

Can I record it?

Yes, up to 4K.

Palette?

All palettes apply; Ember gives an Interstellar look.
