Your eye see a silhouette in the clouds, the trees, the mountains form? shadows?  

hi marianna45 I love to watch the clouds and see shapes that may resemble a papa bear, a mama bear and a baby bear. On other hand I cansee big fluff clouds that look like giant marshmallows. I once saw a cloud formation that was shaped like the outline of the rocky mountains,just perfect rounded shape, also once a cloud that resemble an elephant with trunk, legs and tail, really looked like a huge elephant sailing slowly along in the sky blown by a breeze.

Finding such things in the clouds is such fun! I think there are such things to be seen in the patterns of the graining in wood, the cracks in concrete; virtually anything! I suspect it combines observation and imagination!
