Sorry for all of the posts - the weather is miserable in NYC area. Went from 90s to 40s and raining. Which is what gave me the latest idea. I was working on my Nest thermostat integration. When I logged into the web site they have a lovely blu background with animated rain. It would be cool to have the background change to reflect the weather outside. You could see what the weather is just by glancing at the screen.
I suppose this also could be used to display camera feeds as well although that might get a little busy.
