The next time you stack a cord of fireword, try making a hidden image, like Hungarian artist Gyula Várnai did with this pile of logs:
To build the piece, Várnai piled logs of different sizes, shapes, and colors into this creative pattern to form the silhouette of a crouching man. When standing close to the pile, or viewing it from a side angle, you may not notice the man's form. Viewers must distance themselves from the piece in order to see the human figure come alive on the surface of the wood.
