From the developer:
Spacescape is a tool for creating space skyboxes with stars and nebulas. The program comes with 3 example files in the “save” directory and 10 billboard star textures in the “media/materials/textures” directory. You can export seamless space skyboxes with stars and nebulas, export HDR skyboxes, and more.
You may want to check out more Mac applications, such as Nostromo Array, Njam or rpgng, which might be similar to Spacescape.
