To increase the population by one:

To create some industry and give the lazy buggers something to do:

To improve transportation:

Increase Security:

As the population grows, there are other links that will allow you increase industry, better transportation, increase security, etc. The catch is to get people to click the one unique link that most helps the city.
I dunno, I found it mildly amusing. Every person that clicks the link above will increase the population of 5ertropolis by one. Now, of course, everyone that lives in 5ertropolis drives a euro e28 M5 with s38b38 transplant that gets 40mpg. You know you wanna live there.
