The Sundial screen shows a rectangle with a simulated fencepost at the center. If the sun is above the horizon, the shadow of the fencepost is graphically displayed. If you let the program run all day, the shadow will move in the same pattern as a real shadow.
When the sun goes down, the shadow disappears, and the surrounding rectangle becomes darker until it becomes black when the sun is more than 18┬░ below the horizon.
 
The Animate button on this screen will allow you to speed up the movement of the display to have 24 hours go by in a couple of minutes. After clicking the Animate button, it will change to a Real Time button. Click on the Real Time button to stop the animation and return to the correct display for the current date and time. While the display is animating, you may temporarily "freeze" the movement by clicking on the digital clock panel at the lower right of the map. To resume animation, click on the clock panel a second second time.
 
To the right of the sundial rectangle, the text gives the azumuth (degrees clockwise from true north) and the altitude (degrees above the horizon) of both the sun and the moon. By selecting a future date on a "Calendar" screen, and animating the sundial to the desired time and then freezing the display, photographers can forecast the positions of the sun and moon for a "shoot", or can determine the best times or locations for a "shoot".
