We had this idea just about you can travel in the time in that world. We imagine about how the world works. We told about how to travel, it’s like you can take a transportation like trains to control the time.

Then we discussion about the appearance of the world. We take for there's only some rings around a canter, not like the normal planet. Then we made a model to describe how the world likes.

The direction of the ring’s gravity is always towards the center of the ring. So we draw a big picture of the rings to show what the ring looks like. The trains can run inside the rings and the buildings are around the rings.

The next the day, we started to make another model. We used the pipes to make circles and tied the circles together.

The day after we have made that model, we cut the half, and put the pipes into the holes witch we cut it using the Laser Cutter in the wood. And then we added more pipes. It looks cool.

For the final model, we made holes in the acrylic. We used the 3D printer to make two kind of the things. One is to connect the pipes, and the other one is to hold the rings. All of the things is done.
