It started with the simple wave - like shadow of the neighboring rooftop ...
... and its ability to evoke a deep dark sea ... so when I came home, I couldn't resist the temptation to invent some fish - like shadows ...
... and make them jump inside the GIF. I duplicated the original photograph, cut out the fish shapes from the shadow, and put them on the duplicate ... frame by frame in different positions ... that's how this shadowy animation was made :)
As always in these posts on HIVE, all the work is my work.
