Wet Brick

Sometimes, (well, OK, MOST of the time) it is difficult to find a Blip out here on the Prairie in the dead of winter. So please pardon me as I submit this humble wet brick as my daily blip.
The brick (actually, a brick bat) has been residing in our heated birdbath for a year now and has actually started to grow some things that I am afraid to touch. Thus, the detached photo.
Bet you could not have guessed what I was photographing, if I had not told you.
