Have a look at the spookiest clouds I've ever seen, Asperatus (taken in Scotland) and to make you smile again a Fumulus Snail (taken in Wales).
Thought I'd share two of my own favourite cloud photos.
This was taken at home in Canberra in 2008. I think it is called a tabletop cloud.
I could not believe my eyes when I saw this cloud formation on a trip to Fraser Island in 2007. Now that I have looked through the Cloud Appreciation Society website I think it is called a 'Fallstreak Hole'. Awesome!
Hope you've enjoyed something a little different :-)
