The sensor nodes for interaction are attached to bent clear pvc pipes, which in turn are attached to the cocoons on the white rings. To give these pipes a soft white translucent look, we sandblasted them in this cabin. This treatment uses sand crystals gushing under high air pressure to modify the surface of the material. We quickly found out that round objects aren’t suitable for this treatment, so as an alternative we lightly spray painted them white which still gave us a result to our satisfaction. The sandblasting experience did leave us this nice spacey astronaut picture!
