For the band Dawn Gazers release concert I created an animated background for their stage that at the same time could be accessed via any browser to add a layer of interaction and playfulness to the concert. The site would count down to the concert if one opened it before the show, and on show start it would start a 90-minute color show that simulated a slow sunrise.
The audience could access the site on their phone and use them as digital “lighters”, as concert goes sometimes use to acknowledge the band or take part in the lightshow. The phones would display the same changing colors as the site, and thereby created a unified whole between the audience, band and stage.
Below can be seen a video that demonstrates accessing the web-page about 20 minutes into the concert on a laptop:
