没有人设计椋鸟群飞。没有一个细胞知道自己是豹纹的一部分。给网格一条关于邻居的规则，给一千只鸟一条彼此相处的规则，让没有大脑的黏菌去解开迷宫——结构便凭空涌现。这些是复杂性的玩具：简单到一行即可读懂，深奥到我们至今仍无法预测。按下播放，看整体如何超越其各部分之和。
Four cell states and three rules build clocks, diodes and logic gates as electrons chase along copper wire.
A lattice of stubborn neighbours: each cell keeps borrowing a random neighbour’s opinion until coarsening domains slowly devour one another and the crowd lands on consensus — unless a few immovable zealots flip the whole population.
Thousands of self-propelled specks, each only copying its neighbours’ heading — dial down the noise and a leaderless flock crystallizes out of the swarm.
A 2D Turing machine with internal state on a grid of colours — a single head whose transition table conjures growing spirals, snowflakes, and fractal cities out of an empty lattice.
Hundreds of brainless termites blunder across a field of scattered wood chips — pick one up, carry it, drop it beside another — and with no blueprint, no foreman, and no memory, the litter slowly gathers itself into a handful of growing piles.
Reiter’s hexagonal cellular automaton grows the iconic six-fold snow crystal one diffusion step at a time — from a single frozen seed to a stellar dendrite.
A lattice of species locked in a cyclic food chain — each one hunted by the next — self-organises a random soup into chasing, rotating spiral waves.
Open each lattice site with probability p, watch the clusters, and catch the instant a single giant component snaps across the grid at the critical threshold.
A two-state Turing machine on a grid: one ant, one rule per colour, and ten thousand steps of chaos that suddenly straightens into an endless highway.
A lattice of magnetic spins boiling between order and chaos — cool it past the Curie point and watch domains crystallize out of noise.
Trees grow, lightning strikes, fire sweeps — three cell rules that tune themselves to the edge of chaos, where blazes become scale-free.
The famous oscillating chemical reaction, simulated as an excitable medium — broken wavefronts curl into rotating blue↔red spirals and a stimulus blooms into concentric target waves.
A three-state excitable automaton that never sits still — firing cells leave dying wakes, spawning endless streams of self-propelled gliders.
看一个 0 到 255 之间的单一规则号如何展开一幅无尽的时间织锦——从混沌噪声到分形秩序，直至图灵完备的计算。
看约束传播如何仅凭邻接规则，一格接一格地编织出电路、结与地貌。
数十万个无头的多头绒泡菌个体嗅探化学轨迹，自发连接成最优的运输网络。
在一点上落下数百万颗沙粒，看坍塌规则如何从纯粹的算术中雕出完美自相似的分形曼陀罗。
两种化学物质在环面网格上彼此追逐、相互消耗，从纯粹的数学中自发生长出珊瑚扇、豹纹与迷宫般的曲径。
一个微小的随机神经网络掌管每一个细胞——看它生长、自我修复，绽放成异样的活体纹理。
一种连续状态、连续核的元胞自动机，平滑的高斯卷积将无生命的噪声诱导成爬行、分裂、自组织的团块。
康威的零玩家宇宙——绘制细胞、雕琢规则，看滑翔机与滑翔机枪从混沌中刻出结构。
看分形闪电树如何从纯粹的布朗混沌中结晶而出——正是这条规则雕琢出玻璃上的霜花、珊瑚礁与闪电。
看一锅随机像素汤如何自组织成旋转的螺旋“恶魔”——正是驱动别洛乌索夫-扎博京斯基化学反应的那种可激发介质动力学。
看数百个自主个体仅凭三条局部规则——分离、对齐与聚合——自发汇聚成椋鸟群飞。
数百只虚拟蚂蚁仅凭信息素轨迹便能找到并利用食物来源——没有领袖，没有地图，只有共识主动性。
