Wow! This is pretty sweet. I have a hard time folding a napkin let alone origami. This beautiful work of art was done by antzpantz, who states on his flickr page.
"No no, this did not come from the Origami Calendar box! This was something I folded three-and-a-half years ago while bored one night and not studying. It took three painstaking hours to fold. He stands at 4.5in (11.5cm) tall and was folded from an A3 square- approximately 12x12in (30x30cm)! If I had a larger green square, I'd totally do it again.I found the instructions here soon after they were posted. My original photos can also be seen here."He's got some serious talent!
