I'm calling it "Orbits". The planet orbits the sun every 12 hours and the little moon orbits the planet every 60 minutes. So, you read the hours by observing the location of the planet with respect to the sun, but you read the minutes by observing the location of the moon with respect to the planet. The asteroid orbits the sun with Sunday at the top, so the first half of the week is on the right and the second half is on the left. The rays of the sun shorten as the battery power diminishes. Touching anywhere on the screen displays month, date, hour, and minute in the corners for 5 seconds.
(Positive or negative feedback is greatly appreciated.)
