A mysterious building.
Millions of stories.
Be part of it.
someone lit a window for you
This is a building. Nobody is quite sure what it's for. Anyone can light a window for free and it glows for 12 hours from the last time they visit. For £2 the building keeps a window lit forever with your words on it; for £3 a window you choose exactly where it goes, so people draw things. When the top floor is nearly full, a new floor appears. The penthouse at the top is let by the month. Somewhere there is a red window.
Every window has a link. Send it to someone. That's the whole idea.
The building stores a random cookie so it knows which window is yours, your country (from the network, not your location), and the words you choose to leave on a window, which are public. Payments are handled by Stripe; the building never sees your card. Nothing is sold to anyone.
Throw a party, or pay another month's rent.
The building keeps a log. Something happens every half hour or so, whether anyone is watching or not.
You missed a few things.
