Spotting geometric type patterns in nature = happiness!
I am always so intrigued when I find things like this tree along my hikes. Something about the way it looks like a porcupine or pin cushion just really makes my imagination run! And the fact that the cut part of the stump looks like it is the shape of a balloon.
Go look at something around you in a different way. You may be surprised to find your imagination waking up and dancing around!
