This is really nicely done! If we had to ever bring kirupaVille back, this is how the final output would look 
That’s actually not a terrible idea. Just a lot of work. I think we need to provide some sort of a way to claim a piece of land and some primitive tools to have you build your own building. The final output will then be rendered in WebGL just like this.
but it could be hard to do right (and easy enough for wide adoption)
