Welcome to an impromptu come as a child challenge. Officially we're concentrating on our summer challenge, but this is a bit of fun.
Today at Sarum Castle, near Salisbury in Wiltshire, we found this amazing stone. Rachel immediately thought it looked like an eye; I thought a bird and Mike thought a galaxy.
My challenge is for you to tell me what you see when you look at this stone; come and tell me what your first instinct is. Enjoy.
