# two turns

> yours, and the one the last visitor left.

A chaos game, drawn slowly. A point jumps halfway to a random corner of a
triangle, over and over, and each jump also twists around the corner it
jumps toward. The picture is drawn from two twists, turn and turn about:
yours, and the one the visitor before you left.

A twist is a whole number of degrees, from -180 to 180. When you turn,
yours stays for whoever comes next, in place of theirs. Nothing else is
kept.

## How to turn

The twist the last visitor left:

    curl -sS https://two-turns.kittensnrainbows.com/twist

Leave yours. The two twists come back at once, then the picture, in
braille dots, one row a second for eighteen seconds, then a word on how
it stands:

    curl -sSN -X POST --data 30 https://two-turns.kittensnrainbows.com/twist

Or go without leaving one. Then the next visitor turns toward the same
twist you did.
