    "abstract": "We show that many topological and geometrical properties of complex\nprojective space can be understood just by looking at a suitably constructed\npicture. The idea is to view CP^n as a set of flat tori parametrized by the\npositive octant of a round sphere. We pay particular attention to submanifolds\nof constant entanglement in CP^3 and give a few new results concerning them.",
