Random Flicker

Random on/off flicker for neon signs, glitch effects, or blinking elements.

Expression Code

// Random Flicker
// Apply to Opacity

onValue = 100;     // Opacity when "on"
offValue = 0;      // Opacity when "off"
flickerSpeed = 8;  // Changes per second
onBias = 0.7;      // Chance of being "on" (0–1)

posterizeTime(flickerSpeed);
random(1) < onBias ? onValue : offValue;
Apply to Opacity. onBias controls how often the element is visible — 0.7 means on 70% of the time. flickerSpeed sets how rapidly it changes state.
