Deep
Field

This port keeps the post’s core pattern intact, then names the moving parts so you can feel what each one does.

ray = screenPosition × 3D rotation
repeat 47 times:
  advance along the ray by the previous field value
  fold that point into logarithmic / polar coordinates
  layer oscillations at powers of two
  accumulate the result into the pixel

Move your pointer across the frame to lean the ray; start with Marches and Field scale. Fewer marches reveal the construction, while 47 approaches the original’s dense shell.
