Talk about forward-thinking office design! Twitter, the incredibly popular social networking site, recently moved into a new space in San Francisco's SoMa district and spared no expense at providing its employees with a hip, positive and (most importantly) effective work environment.

Keeping up with global office design trendsetters such as Facebook, Red Bull and Google is no easy task, but Twitter succeeds by incorporating non-traditional elements such as a dj booth, arcade, and awesome looking custom concrete conference tables. Not surprisingly, the entire building is outfitted with Wi-Fi connectivity and the company's now world-renown bird logo.

The following are a few photos taken by actual Twitter employees. Bonus points : Pay special attention to the use of Steelcase office furniture, including the Think chair with alive-seating technology.

Our verdict? Twitter doesn't only know how to design a great looking space, they know how to create an environment that's as innovative as the online services they provide.
