One banner across your crew

Line up 2 to 4 phones. One phone hosts, the others join. The letters run straight across the gaps between the screens.

No account and no server. Phones talk to each other over your local network.

Glow and Beat

A glow stick in your hand, steady or pulsing. Beat listens for the music and flashes with it. Sound is never recorded or saved.

Flashing is held to 3 flashes a second at most. A warning comes first. With Reduce Motion or Dim Flashing Lights on, flashing becomes a slow color change.
