Check out this piece made from 150,000 boxes of push pins. Here's the story:

“If you were looking for a box of those clear push pins on the West Coast around June 5, you now know why Staples was fresh out. 12, a dozen creatives who form an experimental school at Wieden+Kennedy, had purchased them all — 150,000 of them.

351 hours later, 12 had applied the push pins to a 13’6” x 10’6” wall at W+K HQ in Portland, with a message that was inspired by a true story from the legendary Jelly Helm, 12’s creative director:

When Helm was promoted to co-creative director of W+K’s Amsterdam office in 1996, Dan Wieden’s only directive was, “You’re only good to me after you’ve made three tremendous mistakes.”

Hence, their advice to every creative: Fail Harder.”
