PLAY
A shared playground. Everyone visiting this page sees the same board, live — drag the emblems, spin, grow, clone, flip the lamp. Your changes persist for the next visitor. Shift-click any toy to reset it for everyone. Leave a note below — it stays.

Calling cards
Leave a mark that is a bit more you than a note. Pick a glyph, pick a colour, and it stays on the wall for whoever shows up next.
Unmoderated and periodically cleared. No links, one card per visit.
Questions
What is this page?
A shared playground. The pieces you drag, spin and toggle are not yours alone — the positions are stored centrally, so the next person to open this page sees where you left everything, and if someone else is here at the same time you will see their changes arrive live.
Do I need an account?
No. There is no sign-up, no login, and no profile. Nothing is stored about who you are — only what you moved.
Is anyone else here right now?
Possibly not. Traffic here is occasional rather than constant, so most visits are solo. That is why the state persists: what you are looking at is the accumulated result of everyone who came before, and what you leave behind is what the next person finds.
How does it sync without a backend?
The page uses playhtml, an open-source library that attaches shared state directly to HTML elements, with the sync itself hosted on PartyKit. I run no server, no database and no accounts of my own — which is the entire point of the experiment.
Can I break something?
Please try. Everything here is meant to be handled, and nothing is permanent — the shared state is periodically reset, so an arrangement you love and an arrangement you ruin have exactly the same life expectancy.
Where is the game?
Next door. Prism Break is a browser asteroids game with a shared global best score and its own chat — no download, no signup.
