a game engine to test out physics ideas
eg using warped space of 4-bulk 3-brane proper space,
and seeing how that will render,
with the paths and frequencies and wavelengths and speeds that light takes,
and also complex space,
and refraction, and because i waste time
the point of apps and apps making is to make making apps
as fast as making a sketch and to make it a general solution
for apps 2017 onward
