Digital Life 04: When Does a Pattern Become a Thing?

Rule 30 gave us structure.

But it did not obviously give us a thing.

The pattern expanded.

It changed.

Differences propagated.

Interesting global behavior appeared.

But if I pointed at one region and asked:

Is that the same object ten generations later?

the answer was not obvious.

So let’s change systems.

Not because Conway’s Game of Life is more sophisticated.

Digital Life 03: The First Surprise

Tue, 11 Aug 2026 01:19:00 +0100

We ended the last chapter by changing one number.

rule = 22

became:

rule = 30

Nothing else changed.

Same world.

Same single active cell.

Same three-cell neighborhood.

Same synchronous update.

Same periodic boundary.

Same eight-bit lookup mechanism.

Only the rule changed.

And the spacetime diagram stopped looking simple.

There is visible structure on the left.

There is irregularity on the right.

There are repeating fragments.

There are regions that look almost patterned and then break apart.

Digital Life 02: Remove Almost Everything

Tue, 11 Aug 2026 01:08:00 +0100

In the previous chapter we started with something complicated.

A continuous field.

A smooth neighborhood.

A growth process.

Localized structures that moved through space.

Patterns that looked disturbingly creature-like.

That was useful because it gave us a mystery.

Now we are going to destroy almost all of it.

Not gradually.

Aggressively.

We want to know:

How little machinery can remain before interesting organization disappears?

Start with the kind of system we saw in Lenia.

Digital Life 01: Look at This Thing

Digital Life 01: Look at This Thing

Don’t read anything yet.

Watch this.

Something is moving.

It appears to have a boundary.

Different parts of it seem to behave differently.

Digital Life 00: What Would Digital Life Mean?

Digital Life 00: What Would Digital Life Mean?

Suppose we wanted to build life in software.

Not simulate a bird.

Not animate a creature.

Not create an AI assistant and give it a name.

Something more fundamental.

A computational system that begins to exhibit properties we associate with living things:

structure
persistence
response
adaptation
repair
memory
inheritance
evolution

The obvious temptation is to start implementing those words.

We could create:

Cellular Automata From First Principles 06: Patterns as Data — Oscillators, Spaceships and Gliders

Once we can run Conway’s Game of Life, the next step is not to add more graphics.

It is to make the patterns themselves inspectable.

A blinker is not interesting because somebody named it.

It is interesting because it returns to the same state after two generations.

A glider is not interesting because it has a familiar shape.

Cellular Automata From First Principles 03: Rule 30 and the Surprise of Complexity

Cellular Automata From First Principles 03: Rule 30 and the Surprise of Complexity

Rule 30 is a perfect demonstration of why cellular automata are worth studying.

Its transition table contains eight bits:

111 110 101 100 011 010 001 000
 0   0   0   1   1   1   1   0

Start from one active cell and repeatedly apply that rule.

The result rapidly stops looking like something generated by a tiny deterministic program.

Cellular Automata From First Principles 00: How Can Tiny Rules Build Complex Worlds?

Cellular Automata From First Principles 00: How Can Tiny Rules Build Complex Worlds?

A cellular automaton begins with almost nothing.

You need:

a collection of cells,
a state for each cell,
a neighborhood,
and a rule that tells each cell what to become next.

That is enough.

There is no central controller.

There is no object that knows what the final pattern should look like.

There is only local state changing through time.
