This applet relates the sun's illumination angle of the earth globally, with the local sunlight angle experienced by an observer depending on observer's location.
GeoGebra does astronomy!
Drag the Sunlight point to change the Sun's angle (season). In reality, this angle stays within 23.5° of the equator.
Drag the Person point to change the observer's latitude. The right panel shows the local sunlight conditions experienced by the observer, including a measure of how "spread out" the sunlight is on the local surface.
Shift-drag to pan the view, shift-mousewheel to zoom.
