Glorious!
I've long wanted to set up a camera with a Raspberry Pi by the bay and take a picture the same time every day over a year. Because the tides come an hour later every day you'd get a monthly rise and fall while the sun did the same thing over the whole year, and of course the world would go from white to green and back again. Alas I got lazy trying to work out how to power it and protect it from the weather.
That would be awesome if you could figure out how to do it! I would never have patience for that :D
Yeah, the hope would be to do the programming once and then come back for the data a year later. Somehow technology doesn't ever work like that though!
