Randomize

Randomize ON = vivid random colors per letter.
Randomize OFF = all letters use this color.

🏃 Movement

Perlin noise: 0 0 = random walk | 100 = pure Perlin Min speed: 40 u/s Max speed: 150 u/s Speed range applied at each Start. Letters always wrap.

▶ Playback

Each letter gets random speed, spin, and depth-breathe when Start is pressed. Press Assemble (active after Start) to call the letters home — they arc back and breathe together once all have arrived. Reset returns letters home with fresh colors. Space toggles Start / Stop.

Stage 5a fixes a drift bug from Stage 5: after letters assembled at home, they continued to wander due to the random-walk code still running each frame.

The bug (Stage 5)

Once assembly completed, assembling was reset to false but running stayed true. The old guard in moveLetter() was:

if (assembling && s.isHome) return;

With assembling = false, the condition was never true, so every home letter still ran the random-walk branch and drifted away from its position.

The fix (Stage 5a)

The guard is now unconditional:

if (s.isHome) return;

Once s.isHome is set to true the letter's position is never touched again — only SWCharacter.update(dt) runs (for breathing). The word stays perfectly in formation and breathes in synchronized unison indefinitely.
