Pinney started the Cloud Appreciation Society in 2005. Since then, he's been encouraging people to 'look up, marvel at the ephemeral beauty, and always remember to live life with your head in the clouds.' Membership to the Society now includes over 47,000 cloudspotters. Together, they capture and share the most remarkable skies, from sublime thunderstorms and perfect sunsets to hilarious clouds that look like things.

A Cloud A Day is a beautifully illustrated book containing 365 skies selected by the Cloud Appreciation Society. There are photographs by sky enthusiasts around the world, satellite images and photographs of clouds in space, as well as skies depicted by great artists over the centuries. The clouds are accompanied by enlightening explanations, fascinating snippets of cloud science, poetry and uplifting quotations.
