Leo Burnett and Domani Studios have launched a site that supports Allstate and the U.S. Olympic Committee's joint effort to create an Olympic bid for the city of Chicago.

The two creative parties developed an interface that lets kids and adults alike build a virtual playground step-by-step using various accessories and colors. The site was initially conceived as a contest (now closed) where the top vote-getter will have their design actually built within Jesse Owens Park on Chicago's South Side. While the winners won't be announced until March, the public can nonetheless view a gallery of entries for inspiration and try their hand at building a playground all their own.
