City Project introduction

This is a starter page for our new upcoming city project. More info about the project will be added soon.

The City

After some brainstorming we started to build the table where the city will be installed. For that we are going cheap and used material we already had in our space.

Moving building

Our first try to move a building up and down to re-shape the city succeeded. The mechanics are not perfect yet but it's working.
