Talk:Projective geometry

We need some main concrete elements in this article:
- some mathematical content about "What" is projective geometry. i.e. perhaps the basic axioms of projective geometry, and some important theorems. In particular, the Fundamental Theorem of Projective Geometry. Possibly some words about pole and palar, pascal hexagram stuff, degauss's theorem, and the projective coordinates.
- some history of projective geometry. (i.e. its origin from artists wanting a realistic drawing, now know as 'descriptive geometry'.)
- modern projective geometry: higher dimensions and other abstract development that has nothing to do with "projections". Lattice theory...? and projective geometry and crytography...

We have already projective plane, projective space, homogeneous coordinates, Desargues' theorem, Möbius transformation, incidence (mathematics), all of which relate in some way to projective geometry.
How about an article about cross-ratio?
