Very cool watchface. Just got my Pebble, and this is the first face I installed.
Is there any chance you could add an option to fix the local zenith at the 12:00 position rather than the sun?
This way, you could see how close to the eastern (or western) horizon the sun and planets are. The sun would slowly circle the watch face every 24 hours, passing the 9:00 position at sunrise, 12:00 at local noon, 3:00 at sunset, and 6:00 at local midnight.
Just my $0.02. Thanks for reading.
