It's like the tale of a superhero: By day, Gonzalo García Calvo is a musician in Madrid, but by night, he's an amateur origami artisan.
You might be familiar with the art of origami from reading Sadako and the Thousand Paper Cranes in elementary school, or from folding our own clumsy frogs and cranes and flowers as kids. But the vast array of objects and creatures that can be summoned from one piece of origami paper is truly unfathomable to the non-expert.
Calvo told The Huffington Post via email, "I find it fascinating that by changing the steps in the folding process you end up with a totally different model, so in essence, a square of paper has inside of it all the possibilities to be anything you can imagine."
As demanded by the rules of the art form, only folding of the paper is allowed to achieve the stunning transformations, making the results all the more remarkable. "You can fold almost anything with a single square of paper without gluing or cutting it," he said.
