I'm looking for clues/tips/tutorials/etc that will show how to do lightning and 'force lightning' visual effects. The software I've got available is Wax 2.0e, ZS4 and of course, WMM. (buying a commercial package is out of the question, budget requires free software)

I've spent a good deal of time scouring various SE's, YouTube & Metacafe and thus far found zip.

New here so excuse if this isn't in the best area.
