What Happens When The 42nd Wheel Joins The Belt Web? ⚙️ | 9 Simulations, One Piece At A Time

About this piece

Belts wake 42 wheels one at a time, and when the last one joins, the whole web turns as one. Around it: a chain of 301 rainbow links pushed into a spiral groove until it meets the hub, a bouncing ball that cuts a hexagon into a 200-cut gem, 720 red and blue walkers who sidestep their way into clean lanes, 4,000 jumps of a number sequence drawn as rainbow arches, 361 flowers on a climbing vine wall, a triangle that gains a side with every bounce until it is a circle, 300 right triangles that wind into a rainbow shell, and a falling-note piano that plays a whole tune. Every chapter starts at 1 and ends when the last piece is in. No talking.

Every chapter in this one starts at 1 and adds a single piece at a time: one link, one cut, one sidestep, one jump, one bloom, one side, one wheel, one triangle, one note. The number under the chapter title is the simulation's own count in that frame, so you can watch it climb until the last piece is in and the picture is done.

Two chapters run on open rules: the walkers steer around each other and settle into lanes on their own, and the number chapter follows the Recaman rule exactly. The rest keep to a plan so that they finish on time: the ball in the gem bounces off the walls for real but the number of cuts follows a planned pace, the chain is pushed in at a planned speed, the shape gains its sides on a planned count of bounces, the belt web wakes its wheels at set moments, the triangles are added on a timetable and the vine wall is steered to finish blooming at the end. The last chapter plays the melody of Fur Elise by Beethoven (public domain), one falling note at a time, getting faster. The rules, the code and the sound are all original.
