The Redistricting Game! http://www.redistrictinggame.com/

The Redistricting Game is designed to educate, engage, and empower citizens around the issue of political redistricting. Currently, the political system in most states allows the state legislators themselves to draw the lines. This system is subject to a wide range of abuses and manipulations that encourage incumbents to draw districts which protect their seats rather than risk an open contest.

I'm really impressed by the ingenuity of the people who made this game, or rather were responsible for it being made. The game seems like a great tool in raising awareness about this issue and the same approach could work for other issues as well... such as the electoral process perhaps.
