Space Math
Everything is as physically accurate as I can get it. Seed-based rendering means you get the same scene everywhere, so you can share your celestial creations with others and revel in the majesty of space together as Carl Sagan intended.
Slow & Steady
Nebulae billow, expand, and contract naturally, shadows sweep across volumetric space dust, and stars glitter everywhere. The cosmos morph (that's the name, see?) slowly, but fast enough that you'll live to see the outcome.
Lovely on OLED
Everything is smooth and vibrant, no matter how void-black or H-alpha pink your pixels are. Looks best on OLED panels, though, for sure. The larger the screen, the more starscape you'll see. Go on, take a gander at Firmament. I'll wait.
