So, how about a media player that has no border or anything, but is just the screen itself and doesn’t require a projector or anything? From the user’s end, it just looks like a canvas that can display animated PNGs, or GIFs as well as YT videos with the option to mute the audio from the steamed video? This should achieve the desired result, yes?
There will be support for animated canvases (Through uploading a PNG with all the frames of animation laid out), however this also sounds like a decent idea. Media players still have a ways to come before they’ll be as versatile as canvases though.
