The swarm at the top of the home page borrows from many centuries of makers. Here is every one of them we know, with their licences.

The home page’s swarm, as a montage of borrowed images

IOur own work

The swarm engine and its states, the oil strokes, the painted ground, the voxel textures and the civilisation islands were made for CraftWorlds: drawn, painted or written in code, with no third-party pixels unless listed below. The islands contain no third-party images, textures, models or fonts.

A few of the bestiary’s creatures, and some of the drawing code, come from earlier work.
