Shared into a sky you're under. WebRTC peer connection.
This sky is password-protected. Enter its password to see its flares.
Enter a sky code (looks like cosmic-drop-42) and its password if any. Its flares will drift into your view.
A sky is a container — the thing you lock. Flares lit into it are shared with everyone under that sky.
Anywhere skies are invisible on the public board. Share this code — and the password if any — to let others join from any network.
