Since we don't know really know how to work with color, the colors in our Agate and Geode puzzles are pulled from photos [@nervous_jessica](https://mastodon.social/@nervous_jessica ) has taken.

The Agate first grows outward creating a shape, and then flips and grows inward filling it in with noisy offsets.
