Actually I'm waiting for new and imporved unit-boxes... ;) What's your
status?

I'm a bit of two minds about the inside -function.

On the other hand, it's a nice one to ave (and better renamed proximity),
because for many objects it's easy to write one that gives a linear
distance to object surface: and that's something that is going to be very
usefull in any muber of situations later on.

On the other hand, the only reason it *currently* exists in stead of just
inside-p is that I had difficulty getting CSG normals right with just
inside-p. I think we want to have proximity for all objects we can
reasonably define it for, and then try to get as much of csg as possible to
work with just inside-p.

Glad you like it. ;)

However, for the duration I think it may be wiser to keep up with
"baby-steps" to accumulate our collective lisp & CG knowledge pool.

I think that this kind of deferring of major redesigns is something Lisp
shines in: since there is little or on "hardwired" architecture, taking the
shader route should not be too hard even fairly late.
