The idea here is that no matter how great the cause, pro bono work is a stretch for any busy professional, right? With that in mind, Architecture for Humanity proposes that you instead donate a day's salary toward owning your choice of 365 days of pro bono, for-a-good-cause design services around the world. "Think of it as community service plus design (minus the parole officer.)" Own the Day.
For your good gesture, you get to own the day on the Architecture for Humanity website. Once you have made a donation, you can choose the day of your choice, and your name will appear on their sites calendar for that day - as well as a spot on the homepage.
