Building of the Box / Cars

Yesterday i started to build the box and get the physical part of the project done. All i need to do now is to get into the workshop and cut a few pieces of wood and then fix them into place. I have also been to the warehouse and got my final model cars. I have fixed some magnets into them and they are fun to play with as they react to each other. (I have modified one of my failed projects in 389 for this project and it is working perfect.) I have also been able to work through most of my issues with the design of the box. Here are some development images:
