In teams of two we have build our own boat or treehut, and spend the night in them. Seeing the river as a vein of the earth got us inspired and we found that our boat should not only carry people, but also the little animals that find themselves in the river. We design our boat like a waterwheel and made a cover with a volumnial pattern where the water of the river can flow through by the action of turning the wheel. Here is how the water of the river floating through the veins of our boat. Vein voyage!
