Innovation in Sanitation: Sanitation Hackathon

Thankfully, several innovative Sanitation projects are popping up around the world. Take the recent Sanitation Hackathon from Dec 2012, when 1100 developers and technologists convened to address Sanitation problems from the developing world. This featured a collaboration of public, private, and non profits from around the world.

From what I could tell, there was an onsite challenge, and an offsite one for app development. You can track and see the results here.
