I saw this "fish" on a sidewalk in Woods Hole today:
Entirely made from light and shadow - I couldn't resist to photograph it:
Half an hour later, it was gone - most likely forever (feel free to send me a counterexample if you like ;-). Despite working on serious documentaries and visual stories most of the time, sometimes I just like to play around with my camera and take silly pictures. Do I have to worry about that?
