To be frank, it dawned on me saturday night, when I realised that Chris is
using flat surfaces (usually discs) for this sort of purpose in galaxy.inc.
The main problem I had is controlling the shadowing, which is still lacking
and largely empirical.

Indeed. This is just a short test and I suppose that with clever math one
could obtain really amazing and flexible results (which is what Chris
intends to do I guess). It reminds me of Rune's grass texture, actually,
where complex texturing allows for 3d effects. There's a lot of untapped
potential here.
