12 Most Satisfying 2D Simulations 🌀 | 9 Minutes of Pure Satisfaction

Photosensitivity warning: this video contains flashing lights and rapid colour changes. Flashing sections: 3:55, 5:04, 5:56, 8:05. 13 satisfying 2D physics simulations, one after another — every collision plays a note, so the music is the physics. Which one did you watch twice? Tell me in the comments and I'll build a sequel to the winner. ⏱ Chapters 00:00 Blocks it hits fall and pile up, until it reaches the CENTER 00:46 Can the ball escape the spike ring? 01:32 Every circle grows until it touches another 02:18 Same shapes merge until a CIRCLE is born 03:11 Every bounce ×2 and spins it faster — can it hit ×1,000,000,000,000? 03:59 Every star it eats grows back, until NOTHING is left 04:46 Every bump multiplies them 05:10 When a ball fills the circle, the balls DOUBLE 05:59 Escape all 9 semicircles, 6 rounds 06:25 When the pentagon fills the arena, the arena gets BIGGER 06:56 Every bounce leaves a triangle behind 07:42 Every bounce grows the ball until it SHATTERS 08:21 Every 5 seconds it gains a mirror All simulations are real physics, rendered at 4K60. No sound effects were added to the collisions — every note you hear is one impact. Which one was your favourite? And what rule should I simulate next?
