FINITY

Every possible picture,
in order.

A grid of 16 by 16 black-and-white pixels is about the smallest canvas on which pictures still feel like pictures. It has 256 cells, each either on or off, so it can show exactly 2256 different images — roughly 1.16 × 1077 of them, about the number of atoms in the observable universe.

Finite, but only technically. Every letter of every alphabet, every tiny face, every icon ever drawn at this size, and every icon that never will be — each one already sits at a numbered position in the sequence, between oceans of static. If you counted through them at a billion images per second, you would finish in about 3.7 × 1060 years. The universe is 1.4 × 1010 years old.

This page is a small machine for failing to comprehend that.

Each pixel you set free doubles the number of possible pictures. Watch what 256 doublings does.

The rooms we will not build

This grid is the small one, chosen because its impossibility is still almost graspable. We thought about building the bigger ones. We are not going to, and the reason why is the exhibit.

Give this same 16×16 grid full 24-bit color and the count jumps from 1077 to about 101,850 — the atoms-in-the-universe comparison died in the first sentence. One single 720p frame — 1280 × 720, ordinary video — is about 106,658,301: writing the address of one particular frame, digit after digit, would fill a 1,200-page book. One 4K frame is about 1059,924,718. And a two-hour 4K film, taken as a single object, has roughly 1010,000,000,000,000 possible versions — the exponent is itself a 14-digit number. Somewhere in that count is every film ever made, every film never made, and a perfect recording of your entire life from every angle, with subtitles, in languages that don't exist yet.

A bigger canvas would not make the idea bigger. Past this grid the numbers stop being quantities and become typography — the only thing left to compare them to is each other. The frontier you can actually feel is the one in the toy above, and it is already past the edge of the universe.
