In another lifetime, I would have enjoyed going to the links you provided. About 20 years ago, I developed a fictitious society with about 300 constituencies, each with its own unique demographics. THen I ran different kinds of elections to see how the government would have formed. Unfortunately, I seem to have lost that project.
This days, spare time is kind of scarce. I need to promote my concept of government with no political parties. Regardless of how we structure the ballots, the 12 limitations of political parties will always be there.
