If you’ve ever had trouble calculating where the sun hits your house, the SunCalc might help. This Google Maps hack by Vladimir Agafonkin tracts the position of the sun over a location at any point in the year at any time from sunrise to sunset. From the site:
The thin orange curve is the current sun trajectory, and the yellow area around is the variation of sun trajectories during the year. The closer a point is to the center, the higher is the sun above the horizon.
This can be helpful when planting a garden or thinking about heating and cooling your house. Plus it’s fun to play with. [Root Simple]
