I've done the parabolic primary with good results.  It was just a quick
proof-of-concept thing, so i didn't bother with the secondary or eyepiece.
Parabolic reflection is straightforward, but designing a multiple lens
system requires, um, library books and math.  The secondary would also have
been straightforward, but i didn't see the point without an eyepiece.

Warp's project interested me, because i had once tried to trace the path of
a ray of light through a brilliant round cut diamond.
