Windows and Doors showing the effects of the wind.
My son (number one) once wrote a composition entitled 'all my father left me was the moon' (a setting of the Michael Leunig poem). That same son noticed one night that the moon had a halo around it, and begged me to take a photo of it. Through subsequent googling, I learnt that this beautiful phenomenon is termed the '22-degree lunar halo' - whereby light is refracted through high cirrus clouds, causing a halo with a radius of 22 degrees around the moon.
