"I started drawing portraits and it was hard ... so I decided to draw something different," a self-taught Serbian artist writes in a blog post for Bored Panda.
Čuljić's drawings are mind-blowing cases of 3-D art; at first glance, the objects Čuljić creates appear completely real and tangible. But, as shown in a demonstrative video, viewers can watch as the artist turns the paper to reveal an entirely flat surface.
Mashable explains that since showing his work on the Internet, Čuljić "has really enjoyed the 'wow' reactions he's been getting." And wow, indeed.
