A boy of only 15 years from Brazil named Joao Carvalho draws amazing three dimensional notebook drawings. Carvalho ,who is also known as J Desenhos, draws curved notebook lines on the page and then gives additional shades for bringing those to life. Thus, he makes character images that seem to coming out of the page. What is more interesting that, although 3D drawing is a special type of art, he has no formal training in this and learnt it on his own very recently. Just scroll down the page and you would like his incredible creations.
