For my social design issue in the twin cities, I chose to advocate the free children programs at The Walker Art Center in Minneapolis. This might not not typically be considered a "Social design" issue, BUT it is a social design revolved around important sociological issues AND those issues are presented through design ( Film , Lectures, Exhibits, Art projects etc.)
In the past the walker had had some interesting events for children. For example, last October they collaborated with Solution Twin Cities to create an event called, " Move Your World". The event focused on the importance of our youth to be mindful of the present world, the world they will inherit, and how they can improve it.
A regular event at the Walker is Arty Pants. Arty Pants is every first and fourth Tuesday of the month at 11am-1pm. Its a parent-children play date involving interactive art activities. http://calendar.walkerart.org/event.wac?id=3541
An upcoming event is "Film:Girls in the Director's Chair". The film helps kids "explore and connect the dots between the messages in the mass media". http://calendar.walkerart.org/event.wac?id=4250
