The front section of the foundry is nicknamed "French Laundry," a reference to white-run laundry businesses and a callback to the space's previous life as a Laundromat. Workers embrace the ironic undertone of the name given the collaborative nature of the space.

Working at the foundry
Someone is clearly a "Star Wars" fan, with a Death Star on display behind a welcome sign.

Much of French Laundry is made up of uniquely shaped furniture that's low to the ground. It provides a more intimate feel, with people getting close to the floor as they work together.

A wall made of cable
One of the more unique features of the foundry is a sliding wall made of cable lines tightly strung next to each other, making for a flexible divider that separates, but doesn't close off, the room.

Everyone is welcome
Entrepreneuers, programmers, and AT&T executives and employees regularly visit the foundry. One developer's dog is even welcome.

Quietly working away
It's quiet during a recent visit to the foundry. Only a handful of developers are busy in the corner typing away at their computers. The foundry is virtually a 24-7 operation; people come in later in the evening and will often pull all-nighters.

The foundry played host to a Facebook-related hackathon last month, with nearly 200 developers crammed into the space and working on new apps for the social network (it was rearranged to accommodate the crowd). The Palo Alto facility focuses largely on apps.
