Inc magazine's World's Coolest offices series profiles the offices of Missing Link, a South Africa based company that designs corporate presentations.
From the article:
The materials and activities you choose to include in your office set the tone for how employees treat their work. For Missing Link, which prides itself on its employees' relentless creativity, that meant including things like an in-house tattoo parlor, a fire pole, and even a shooting range (meant to relieve employees' stress, of course).
It just goes to show that encouraging your employees to be more creative can be done in many ways.
