Adapted for Pebble Time Round
Changed direction of contrast gradient to be the same for both hour and minute hands, as interestingly, this seems to be much easier to read. The original version where minutes were dark->light in clockwise direction but hours were dark->light counter-clockwise. Apparently, this made it much harder for the eye/brain to "see" the hands at a single glance.
First release, written to celebrate arrival of my Pebble Time red today!
