Completely different architecture, but would be amazing if another device could control what message (or photo, embedded video) is displayed.

There's a huge industry around digital signage and I've always felt it could be replaced with a simple Chromium kiosk + auto-refreshed webpage content. There's really no need for expensive HDMI connections or custom video streams when we already have browsers.

I worked for a company creating apps for Kiosks that used SiteKiosk. It was a tight sandbox around Internet Explorer on Windows. This was 2014. Browsers are highly viable but properly locked kiosk mode wasn't. We used custom enclosures for $$$ with micro ATX Intel. Now Raspberry Pi or smaller could run circles around those workloads.

That period was a fun time and one I think about all the time. The profit margins and costs have come down so much I don't know if an equivalent workload or company would stay afloat as long.

I'm working on TheOpenPresenter for this, do give it a try. You can pretty much open the landing page, scan the QR code and you're set. It's also open-source and pretty mature now.
