my first post .. I am keen on povray because I can, potentially at least,
program what I want .

I have two things I want to accomplish

* 3D arrows, bent and wobbly and "cute". With a bit of "character". I
thought maybe I could try Chris Colefax's bender, but I can't even get a
basic arrow going . should I start with a cone for the head and a cylinder
for the shaft? how about different "slopes" on the base of the cone and the
side?

Some starter code would be nice .. I am having trouble visualizing/guessing
the function calls I need, let alone the appropriate arguments (size and
location etc)

* ornate picture frames, like you might see in an art gallery. I got as far
as thinking one might make some basic material with a routed or molded
profile, and then cut it at 45 degree angles and fold it - just like you
would do if you were woodworking - but I have not the foggiest notion of
how to write this code.

Again, if someone can help me here .. I think I can probably make progress
on my own once I get a basic framework.

thankyou

Welcome!

There are many ways to achieve this. You can "draw the outlines" and use 
the prism to extrude the arrow. Or use the 'spheresweep' object in 
combination with a cone. Or use blobs and splines to build an arrow. 
Thinking of blobs, you could use arrows found in ttf fonts and process 
them with Remko de Korte's Softtext http://www.xs4all.nl/
~remcodek/softtext.html  Then, with some macros you can bend the arrow 
any way you want.

Again, use the 'prism' object to extrude the profile you want. Then cut 
off the ends using a difference and boxes.
