Leonardo da Vinci Nail Mosaic

According to the Guinness Book of World Records it's the world's largest nail mosaic.

You could look it up.

Saimir Strati (above and below),

a 42-year-old Tirana (Albania)-based artist,

made the piece (top) in August and September of 2006.

"Using industrial nails, the artist recreated [a] self-portrait of Leonardo da Vinci

using nearly 400 kilos [880 pounds] of nails over a 2 meter x 4 meter [6.5 feet x 13 feet] surface.

The technique resembles digital photography, in that each nail represents a pixel."
