Is there one of these around for beginners? I was trying to make a '2d' 
heart using a sphere_sweep but it's looking rather . . . bad :) TIA.

Well, there's the entire "Spline Based Shapes" section in the beginning 
tutorial included in the documentation...

Yea I saw that section, but doesn't help me much, my problem lies in the 
fact of figuring how to calculate the points and all.

There aren't any special calculations, you just position them to make 
the shape you want. Just move them around and see how the spline reacts.

Try SpilinEditor, a nifty little utility available here:
http://www.flashnet.it/users/fn027571/spil/main.html
Very handy for making complex splines.  While the program only does prisms &
lathes, you can copy to the clipboard and then paste into POV and change to
any kind of spline.  I often also use it for sphere_sweeps & splines to make
paths.
