Pendula - Chaos & Sound

Pendula is a relaxing digital toy that turns the physics of the double pendulum into sound and light. A double pendulum is just a pendulum hanging from another pendulum — yet it moves in a way that never repeats itself. Scientists call it "chaos." Pendula draws that chaos as glowing light trails, and every time a pendulum crosses a string, it plays a gentle musical note. HOW TO PLAY - Drag a pendulum up with your finger and let go - Then simply watch and listen — no two runs are ever the same MAKE IT YOURS - Choose 1 to 4 pendulums, each with 2 to 4 links - Every combination creates a different dance and a different melody 9 SOUND MODES - Scale / Major / Japanese (koto) / Ambient / Minimal / Lo-fi / Bell / Arpeggio / Synesthesia (sound & color) - Every mode is tuned so the chaos always sounds pleasant KIDS' SOUND PACK (one-time in-app purchase) - Baby Mode: farts, pops, and other funny sounds that babies and toddlers love - Animal Mode: cute animal calls - One single purchase unlocks both modes — no subscription 4 VISUAL THEMES - Neon / Aurora / Sunset / Mono PERFECT FOR - Ambient visuals in waiting rooms, cafes, and shops - Winding down before sleep - Giggle time with your little ones - A first, beautiful encounter with chaos and physics LANGUAGES English, Japanese, Chinese, Korean, French, Spanish, German, Portuguese, Russian, Arabic Note: Pendula shows a small banner ad at the bottom of the screen.
