A portrait of Leonardo Da Vinci, created by artist Saimir Strati using industrial nails, is displayed at the International Centre of Culture in Tirana August 23, 2006. Strati, 40, is using some 500,000 industrial nails on a 8 sq m wooden board to create what he hopes will be entered in the Guinness World Records as the largest 3-D nail mosaic ever attempted. The work will take around 25 days to complete. (Reuters)
