One thing I really liked about AppleTV was the photo screensaver that would slowly scroll photos from your iPhoto or iCloud collection at differing speeds and z-indices.
Since I ditched AppleTV, I've been trying to create a Roku app/screensaver that does the same thing, fed by some cloud-based photo library (currently Google Photos, but someday Flickr).
This app is the Sinatra back end to the Roku app/screensaver.
