Drawball is a social art project in which users could contribute their own graffiti art to a community graffiti wall.  You can no longer contribute to the wall, but you can watch a time lapse replay of the entire project as it progressed.

 Over the weekend, over 200 people helped build a playground for the Harold Colbert Jones Memorial Community Center. It took over 12 hours to build the playground. We moved over 176,000 lbs of mulch, mixed about 7 tons of Cement and built a swing set, climbing wall, jungle gym and a big fort with multiple slides.

Playground in Chicago Heights.
