But the show really amped up when everybody realized how it was making crescents out of everywhere where the light was filtered by a shadow, especially in the dappled shadows of leaves. At its peak, it made the edges of one's own shadow slightly warped and curvy and that coupled with the strange dim light gave the whole evening a magical air. People were dancing to their shadows and playing with the reflections on their clothes. After a while, if you stared at the crescents in the shadow of the tree, they started to have a 3-D effect and pop out, like little hillsides on a map or a crowd of ghostly hooded figures. It was pretty cool. When we were leaving, we ran into a guy who had a piece of welder's glass and we were able to look directly at the sun through it and see the eclipse directly, which ended the whole event perfectly.
There are some higher-res photos of the ghostly crescents at the bottom of the page that I took with my phone that may give a better sense of it.
