Well, it was just a wild fancy :)
Actually, it could be implemented as a different frontend
to the same underlying library, but this would be (if done)
a project for another time.

I think it's feasible and beneficial.

This could be a nice "warm up" before the main work.
Unfortunately I've never studied hyperbolic geometry,
but I guess that I could learn the basic ideas
needed to start implementing it fast.
I've given a quick look at the two Pointcar=C3=A9 models and the Klein one,
everyone has its upsides and downsides, but I wonder how
building a projective object would work.
If I understood correctly I should now look for a mentor and submit my
idea to the wiki, is this right?
