The internet picture frame: a high-quality LCD screen, a little bit of code that can dial out, retrieve image files, and display them. All you need is a phone line and AC power.
This is actually pretty interesting. My parents have had one since Christmas and we stuff pictures in it as often as we get any processed (digital cameras are not in the budget right now).
But the actual process is pretty simple: you log into their website, upload files through your browser, and watch the sunset while it all happens.
