Eric Daigh's portraits (each made entirely out of about 25,000 push pins) aren't just impressive because they took a lot of time to make - they're knock out awesome works of art, too. What's more, they're also pretty large, at over a meter tall each. And what's more, I bet there is never a scrap piece of paper left unpinned in Daigh's house.
