I recently met John Sebes, co-founder of the Open Source Digital Voting Foundation. What are they doing? In his words, while the rest of the world was running around in a panic about the problems with electronic voting machines, he decided to do something about it.
Their goal is to design a voting system that will be secure, reliable, able to do a vote recount and will be open-source so people and inspect the design. It will earn the public's trust.
If you are a designer, you can help with the design.
If you are a developer, you can work on it.
If you are a believer in fair elections, you can contribute to bring this idea to fruition.
