You’ve entered
Æther
Mercury
A single drop of liquid metal, hanging in the dark. It keeps turning toward you. Tap anywhere and the air ripples. Press and hold, and it'll stretch out to reach you.
Tide
Then it spread out into a sea with no bottom. The higher you go on the screen, the bigger the waves get. Press and hold to whip them up.
Lattice
Under the water, it grew a skeleton. The shape is called a gyroid, and it turns up in real life inside some butterfly wings. You're drifting through it now. Press and hold to speed up.
Crystal
Next it tried making something solid: a crystal built out of mirrors, folded in on itself. It doesn't take much to break it. Press and hold and it starts to shake. Keep holding and it shatters.
Loom
This part is yours to draw on. Every line you make gets mirrored around the center, then fades. Leave it alone and it draws by itself. Press and hold to split the mirror, and keep holding to split it again.
Source
None of what you just scrolled through is an image or a video. It's all math, running live on your device, and that includes the music. This is the code that makes it.
This room is the first page of a world that is still being written.
Every universe makes a different planet. Hold to spin it, or roll a new one.
