John Mars and I incidentally came up with the same idea for a week-long class project. Essentially what we made was a digital sun dial that understood the users location and the location of the sun. The watch can also keep track of its orientation, and thus cast a digital shadow which will only cast over the correct time when properly aligned as a sun dial should. The project proved to be a very fun challenge, requiring us to learn the pebble API and also the math that goes into a sun dial and shadow casting.
