This weekend I was working at the first Random Hack of Kindess mundial edition. There were 4 people in our team and we worked on a project called Urban Fact (Fato Urbano in Portuguese). The main idea of this project is to emphasize GOOD orBAD facts in your city. If you see someone throwing the garbage over the streets, just take a picture and post it on twitter using #urbanfact hashtag (or #fatourbano). This picture automatically goes to the project website, where people can vote, comment and share with friends.
