I had this idea years ago! I'm glad someone finally did it. One thought. From a philosophical point of view, I would want this to be something that "lasts forever". So it would be nice if it were solar powered and ran off of an SD card rather than being web-based. Just an opinion from an HN extremist - take it in context. Still, it's scratching an itch for me. Your website is down so I didn't see how much it costs but I'll check back in a bit.
Thanks for your input. I was thinking about a way to have it powered by ambient energy. It is hard to integrate the solar cell in a way that it does not distract from the actual picture, though.
Could try extracting energy from radio waves with a wire antenna around the frame (it's not a lot, but for charging some sort of battery it could work)
Also, get behind a CDN ASAP!!
