Solar Shadows

This interactive map visualizes the trajectory of shadows cast by a hypothetical stick over a full year.

Click anywhere on the map to place the stick. The visualization draws two sets of curves:

• Analemma Curves: The paths connecting the shadow tip at the same exact time of day (e.g., 12:00) across all 365 days of the year. Note the awkward breaking points in the curves due to daylight saving time.
• Daily Sweep Curves: The paths the shadow tip follows from sunrise to sunset on a single day, sampled periodically throughout the year.
