13 Most Satisfying 2D Simulations | 9 Minutes of Pure Satisfaction

Thirteen simulations, one rule each, and every single collision plays a note. Spikes that grow every time they freeze a ball, a square that becomes its own box, two spirals that get faster until the ball hits the centre, and a door that spins faster with every escape until the ring can't hold. Which one should get a full episode? Tell me in the comments. ⏱ Chapters 0:00 Photosensitivity warning 0:03 Every freeze grows the spikes — can the ball escape? 0:36 When the square fills the box, it becomes the box 1:09 It gets faster until it hits the centre 2:00 Every ball it eats makes it bigger 2:36 When the triangle fills, it gets bigger 3:03 It gets faster until it hits the centre (rods) 3:53 Every bounce doubles it — can it hit x1,000,000,000? 4:27 Each escape spawns 3 and spins the door faster 5:05 Both gain a side per bounce 5:52 Simulation ends when the circle is filled 6:56 8% chance to split — which colour takes over? 7:37 Two balls, mirrored into a kaleidoscope 8:10 The ball grows with every bounce until it can't anymore Rendered at 4K60. No music track — the soundtrack IS the collisions. All simulations are real physics, rendered at 4K60. No sound effects were added to the collisions — every note you hear is one impact.
