Photo frame / info center

I have an old laptop with a broken hinge. It runs Linux and is reasonably fast and silent.

I want to convert it into a photo frame and info center ( cycle through photo library, show /edit calenders, show weather). It has a webcam, so a neat feature would be to activate the screen when somebody walks by. Even better would be personalized experiences based on image recognition, Text to speech, voice recognition, everything working offline....

Most of this is already available as FOSS. So starting is easy. Just have to place the laptop and keep it running.

I was planning on using DigiKam and a browser as a start.

Any hints to open source projects doing part or all of that will be appreciated!
