Crowd light show
Audience phone screens lighting up in sync with a show, turning the stands into a giant screen.
In a crowd light show the stage lighting spreads across the whole hall or stadium: phones switch to the same colour at once or form waves and images across the seating.
In Superevent's Crowd Light Show (CrowdLight) module every phone receives the same small state packet and works out its colour from its own seat. The packet arrives over the internet (socket) or offline, through BLE broadcast from transmitters fed by Ethernet and PoE. The show is run from the panel or from a lighting desk over Art-Net and sACN. Because the price depends on the venue and hardware, it is set by quote.
