Sundial: Make the Most Out of My Light

Sundial [enlarge]

One of the most efficient ways to tell time, a simple mechanism that needs no cogwheels, no pendulum, no springs and no winding: to follow the shadow of the sun cast upon a numbered scale in what is known as a sundial or a sun clock. This one I found in a town nearby called Castellterçol. There are some in Barcelona too but they tend to disappear.
