interesting concept: add a virtual town link to your blog, every visitor or click adds a house and inhabitants to it, and the village grows. As soon as you have enough inhabitants, you can switch from building houses to industry (which will create crime, pollution etc.) and just play around with it, a bit like sim city. So here goes: Welcome to Homicidal, France (yeah, sux, it's in French, but you can follow the concept).
UPDATE: it's actually slightly cooler than I thought, to spend funds (that each click brings into your town) on security, industry and commerce and so on, you're given other links, which you can put on your site. So visitors can influence the development of your town as well. Like said, pretty interesting and a lot more fun than Google Analytics.
