This seemed like the perfect light-hearted photo to get us through one more day until Friday. Flickr user zachstern has already proved his mastery with the infrared lens, but usually sticks to ethereal landscapes. This time he headed over to the zoo to capture the orangutans swinging madly in their Yeti get-ups. I have no idea what’s trailing from his foot, but the whole image is a fantastic “what the heck is that??” EXIF.
