Brian Chan has a knack for folding squares into other stuff. Every one of these insects (or sea creatures) is crafted from a single piece of paper, usually a square. Aside from being astoundingly complex, Chan’s work is also easily recognizable: look at the blunted folds, heavy wrinkling, rolled limbs, and choices in paper. Flip through the artist’s Flickr stream a few times and you could probably spot a Brian Chan origami creature on sight out in the wild. (Which would be more welcome than meeting the living versions of most of these in the wild, probably.)
Chan also folds barnyard animals, dragons, fictional characters and various other awesome things. Check out his work on Flickr.
