Cloud-watching

I really enjoyed this 3 minute presentation on the guardian website about cloud watching. It's by Gavin Pretor-Pinney, who has just written The Cloud Collector's Handbook. He obviously has a lot of passion for the subject, but it's the pictures which stand out for me: they capture how impressive cloud formations can sometimes be, and as the man says, they are really a collection of memories, rather than a collection of clouds. Looking at the slideshow was very soothing. Perhaps I'll do some cloud-watching this afternoon.
