I'm not sure whether this wooden canvas of hammer and nail art would be considered mosaic, sculpture, or architecture, but regardless, it's pretty impressive.
Through the use of different nails and elevations from the wooden surface, the artist (or carpenter?) creates a unique textured effect for this 3-D image.
Implications - Materials and methods are always changing in the art world, but the use of classic hardware like hammers and nails could indicate the way in which traditional methods of building and construction are being superseded by more modern technologies. By using seemingly mundane objects in art, consumers are given the opportunity to admire and appreciate these tools once again.
