Behind the myriad of random events, does an unchanging order exist? The Central Limit Theorem provides a positive answer—when countless independent coincidences are superimposed, necessity quietly emerges. As Galton's pegboard reveals: each ball's deflection is a purely random choice, but after traversing layers of pegs, they converge at the bottom to form a perfect bell-shaped curve. This is the most elegant proof of probability theory: the uncertainty of the individual precisely creates the deterministic laws of the whole. We have condensed this statistical marvel into the interactive installation "Randomness and Order" (2100×1800×2200mm). Upon activation, hundreds of two-colored balls rise to the top like a constellation, then cascade down, colliding and leaping within a precisely calculated peg array. The installation features a specially designed two-level observation system: a panoramic view from the front showcasing the macroscopic scene of the balls converging into a river, wh
