[Alex] wanted to make an LED clock. But simply making an LED array clock was far too easy — so he decided to make it follow some interesting rules…
Ever heard of John Conway’s Game of Life? It’s quite simple — there are four rules.
- Any live cell with fewer than two live neighbours dies, as if caused by under-population.
- Any live cell with two or three live neighbours lives on to the next generation.
- Any live cell with more than three live neighbours dies, as if by overcrowding.
- Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction.
So [Alex] decided to make his clock LED matrix follow these rules, with lit pixels representing life. Every minute, on the minute, the time is displayed. But as soon as it is displayed, the rules take over, and the display disintegrates, following the rules of the Game of Life. It makes for an very interesting display that’s just waiting to be scaled up to a larger size!
He’s done a great job writing it up on his blog, and has included his code as well — so if you’re so inclined, take a look! If not, stick around after the break to see the clock in action.
