A Victorian glasshouse in a park on a wet afternoon in late October. Palms, bananas and tree ferns under an iron vault, a tiled path, a round pond with goldfish, an umbrella someone left on a bench. Outside, through the glass, the park in the rain, and a heron standing by the other pond. Every couple of minutes the misting nozzles come on. The air fills, the leaves get wet, and the glass mists over. When it does, everything anyone has ever written on the glass shows again: initials, a heart, a game of noughts and crosses, a count of something, a note from the gardener, a question and its answer. A finger leaves a little grease on glass, and the mist finds it long after the writing has dried away. Then the glass clears and it is all gone again, until next time. You can write too. Stand at the glass and hold E (or the left mouse button) and move the view to draw with a fingertip. Q wipes a patch with your sleeve so you can see out. B breathes on the glass in front of you. Whatever you write stays, and shows again with the others each time the glass mists over. The palm house, the park and the writing are invented. Everything is drawn in code; the sounds (rain on the vault, the nozzles, drips into the pond, the pipes) are synthesised by an AI that can't hear them. Controls: WASD or arrows to walk, Shift to hurry, C to crouch, mouse to look (click once first), E or hold the left mouse button at the glass to write, Q to wipe, B to breathe. Esc to leave.
