any ideas how to create a neon sign using maybe a hollow cylinder filled
with emitting merdia. the problem is how do you "bend" the tube (cylinder)
without resorting to complicated mathematical functions...i know i'm lazy.

Sounds exactly what sphere sweeps are for... :)

yes, spheres sweeps or (depends final forms) parts of torus...

I'm kind of new to this, but I think you'd also be able to use e.g.
cylinder-sphere-cylinder if you were doing simple 90-degree bends by
doing a merge/union CSG, if I remember correctly.
Just my two cents.
