In this May 12, 2017 photo, Pupy, an African elephant, stands in the doorway of his enclosure at the former city zoo now known as Eco Parque in Buenos Aires, Argentina. A year ago the 140-year old Buenos Aires zoo closed its doors and was transformed into a park. The first director decided that the animals should be housed in buildings that reflected their countries of origin. A replica of a Hindu temple was built for the Asian elephants.

The illustrations created by Joao Carvalho are not just simple 3D drawings. By making it look as if various characters were drawn on regular note book paper, Joao fools our minds into thinking that the flat objects we see on the picture are actually 3-dimentional. To create these pieces of art, Joao first draws the lines of the “notebook” paper already bent, as if they stretch over the object that is about to be drawn. Then he applies shading and his masterpiece is all done! By looking at his pictures it is almost impossible to view them not as simple 2D drawings, but as real 3D objects. (Photo by Joao Desenhos)

What do you imagine when you look through a key hole? Do you imagine seeing a Wonderland with a sinister Queen of Heart ruling over a magical kingdom? Or you might imagine an eye staring back at you, if you’re a fan of horror movies. Least of all do you expect seeing a picturesque view of St. Peter’s Dome, perfectly framed by green hedges. Is it a lucky coincidence, or was it intended by the maker? We might never know. However, this became a curious sightseeing spot for many tourists who visit Rome. Thus, if you’re ever in the area of Priorato dei Cavalieri di Malta, be sure to peep into this key hole.
