Feeling a little blue? Flickr user Pa-ya-so packs a number of common zoo images (the little kid with ice cream, the picture taker, the folks bending forward to get a better look) into one shot here, but all in silhouette, framed by that intense aquarium blue, and framed again by the cinematic letterboxing of the top and bottom of the window. We also like how the seal seems to be looking at the people with as much interest as the people have for the seal. EXIF.
