New York City to be precise. Now this is a cool idea and an interesting twist on building blocks for kids. I think it would be fun to make a set of these for several cities. And then you could mix and match them (kids will anyway), and have fun naming the new cities, Bost-Angeles and York-Cago and Mi-Lanta (wait, that's taken), Lant-Ami. Even Des Moines, Iowa has several building with a distinct enough profile that Iowans, at least, would recognize them.
If you decide to make some of where you live, send me a photo.
City in a Bag is available on line at Muji.us. The tallest building is 4", but the cars are really tiny, and would present a choking hazard. You could make you cars larger. And make a Godzilla figure too, just to spice things up.
Being a woodworker is being part of something much bigger than just a guy in a shop. There's a world of woodworking design, art, and culture. I think that's as interesting as the working with wood itself.
