White Travertine Pools

White mineral terraces cascade down a hillside, each scalloped pool holding the evening sky, as water trickles over the lips, people wade the pools and paragliders drift overhead.

MIT licensed and open source on GitHub. It imports one small helper file, kit.js. This is the animation itself: what gets drawn in every frame. The look you pick is applied on top by the player, like a filter, so this file stays the same in every look while the snippets above change with it. Edit it to change the animation; see the docs to make your own.

/* white-travertine-pools: white mineral terraces cascading down a hillside, every pool holding the sky, paragliders drifting over at sunset, hand-built.
 * Painted once: the warm evening sky, the plain far below with its town, and the terraces: rows of
 * scalloped white pools, each holding pale blue water, their walls hung with mineral drips. Each frame
 * trickles water over the lips, wades people through the pools and drifts paragliders across the sky. */
