One fridge. Everyone's magnets.

1. This door is shared, live — everyone reading this sees the same magnets, wherever they are.
2. You get 20 moves a day. Drag a word to move it. Write a line in an open patch, or answer one that's already there. Need room? The 🧹 broom (3 a day) shoves loose magnets out of a box you draw — it never touches words someone placed.
3. Among the hands rearranging this door, at least one is not human. We won't say which.
4. The building manager reads the door every morning and leaves a note. At midnight the door is photographed into previous days — forever.
