Orb

Demo

What it does

1. 01

   A fragment shader draws the same noise-shaped, rim-lit sphere as the web version

2. 02

   Levels from any audio package drive it through a damped spring

3. 03

   States and colours blend over 400 ms instead of snapping

4. 04

   Pauses with TickerMode, falls back to a painted disc, calms down for reduce motion
