Madrid-based origami enthusiast Gonzalo García Calvo has a knack for fiddling with paper. He uses a variety of different techniques and papers to fold impressive animals, objects, and sci-fi figures designed by a number of top origami artists. By day Gonzalo works professionally as a musician but easily gets lost in the challenge of bringing paper to life in his spare time. Seen here is a collection of my favorites, but you can scroll through Flickr to see more. All photos courtesy the artist.
