But yes, I do not like tensors, and my effort will be towards a "classical" extrinsic description of general relativity. The main obstacle I am facing right now is that I don't have the necessary time to study the material I need (mainly tensors, alas), in order to make my theory understandable to mainstream physicists. I am thinking of enlisting the help of Physics Forums people, yourself included :-) . We'll see how it goes. Hi Carl,

I wrote the above linked gravitation simulator to compare different theories of gravity around a point mass. So far I've got Newton, and two coordinate charts of Einstein, the usual Schwarzschild, and the Painleve coordinates I prefer. What's different about the above is that the simulation is written as equations of motion rather than geodesics on an affine parameter. This is much cleaner in certain ways. It is also more elementary because it avoids the need for tensors. I get the impression that your version of GR will also avoid tensors, so maybe it will be easier to simulate than most people. When we get the thing simulating, I'll send you the source code and you can modify it as your ideas change, and host it on your site. It's very visual, and since it has simulations for most of the checks of general relativity, it's a natural for you.
