An expeditionary force from the Republic made the trek down to Facebook headquarters in Menlo Park for Photo Hack Day 4.

Facebook has a wall for all to doodle upon. And a camera to watch what you were doodling! Please Note: Due to technical limitations, Facebook Wall posts cannot be deleted. Thank you.

"Yo dawg, we heard you like walls...."

Hackers Gonna Hack.

From our table, we were constantly reminded that “Fortune Favors the Bold” and to “Move Fast and Break Things.” Mabel would love to have the Fortune poster; Alex wants one that says “ Fortune Favors the Condensed.”

We donned the traditional neon hoodie garb of the Republic to aid recognition. Call it a user affordance.

Helping Andreas with the Mozaify app, in front of the Focus poster...which is out of focus. (in)Focus: ironic juxtapostion as catalyst towards a dialectical of the essential tensions of the predominant social media. Oh wait, that's just a fingerprint smudge on the iPhone camera. I was eating nachos earlier, sorry.

Yuki & Mabel stayed up all night designing! [Not Pictured: Alex]

Amateurs bring their own mouse. Professionals bring their own mouse pads.

Hack Complete. Group gathering at the courtyard on Sunday after hack submissions at noon. We were being herded off to another part of the Facebook campus for the hack demos & prizes.

Socializing with new friends.

This is what we look like with no sleep.
