More links regarding Neil Greenberg's Fake Omaha project.
Not really a conceptual city, its a fictional city, but I think it should be of interest to others on this forum.
The goal of the project is to draw people such as ourselves to collaborate and make an ink and paper city into a real , living city. Even though you can participate in the development of the city, by opening your own "businesses" or pitching ideas to the "city planners", it still functions as a blank canvas for anyone who enjoys urban planning.
