What I'd like to see is 4K images from my favourite photographers on Instagram, displayed from a small device that I can plug into a spare port on a TV (or a smart TV app, I suppose). I'd pay a subscription for that (of course, I might be the only one :))

That's essentially the idea of what we were building. Ran out of time due to moving and job change, but I had that working great on Chromecast. Chromecast at least then was awfully clunky though.

For some demos I used cheap Android-powered dongles (like the Amazon Fire Stick, but wide-open rootable Android) to make a plug-and-play display device. With some small work it would be a fun Kickstarter.
