We knew that there would be use of wormholes and folding space and the screens would need to depict this in some way. The production designer Hugh Bateup liked the notion of 3D weather maps. The iso lines in weather maps are normally used to describe weather fronts, but he liked the idea that they represented gravity or other invisible forces that the alien characters knew how to read. Using those organic forms we could reveal ships de-cloaking or the fabric of space being folded to create a wormhole.
