For our first nifty view, please see art made with flocks of sheep, crazy shepherds, and very, very well-trained dogs. Simply awesome, and totally worth calling your kids over to see.
For our second site, I must caution you that a few of the pictures are possibly NSFW, and merit review before calling the kids over. In my house, they came running when they heard the hysterical laughter. The site, probably known to many of you, is Picture Is Unrelated, in which they have compiled an impressive growing collection of those odd photos that you sometimes find, where the subject does not match the background. Be sure and page through their archives, and read both the headings and the captions, which make the site. Made of win.
