Public PI Microsite

Orbit inside 4.29 billion indexed digits of π.

Search your sequence, inspect its position and recurrence, then turn the result into a downloadable postcard built for people who actually like staring at number patterns.

Sequence Observatory

Search a digit sequence in π

Scope is the first 4,294,967,296 fractional digits. Positions are 1-indexed and overlapping matches are counted.

Connecting to the indexed PI backend...

First position - waiting for a search

Occurrences - within the indexed PI scope

Rarity signal - sequence probability intuition

Digit signature - sum, unique count, symmetry

Context window

The first hit will glow here.

Search a sequence to inspect its neighborhood.

Occurrence Trail

Where it lights up

Trail keeps the sampled hit positions. Heatmap turns the same sampled hits into a density proxy where tighter gaps glow hotter.

No occurrence trail yet.

Postcard payload

Every search can become a postcard

The postcard generator uses the current sequence, position, occurrence count, and a rotating PI fact. Change the palette and export PNG.

Postcard Forge

Build a PI postcard

This renderer now follows the old WEBPI logic: the found sequence is placed in the middle of a real PI snippet and the remaining digits fill the bitmap grid around it.

Waiting for a valid match before rendering the postcard grid.
