In an ongoing series entitled Shaping Clouds, Argentinian artist Martín Feijoó takes photos of clouds and then draws what he sees on top of them. On his tumblr project page, Martin explains:

When I was a child I was told that clouds’ shapes were created by expert balloon twister clowns who live in the sky, so that they can keep entertaining children. On my last trip to Mexico I remembered this and I started to photograph clouds on the road. The result is Shaping Clouds, a series of illustrations where I drew the first thing that came into my mind when I saw these clouds that I imagine someone made for me.
