Just created a script for generating spirals:
Creates 3 types of spirals: Archimedean, Logarithmic and Fermat’s. Nothing particularly spectatcular, but I’m chuffed cos its my first script made in Blender/Python. Chears to Stefano, borrowed his method for building the gui from BMG - very cool script.
Next thing I want to do is allow a profile to be specified, so that one create spirals with a 3d shape.

Ok, its sunday and I ws bored so have modified script to run with latest official unstable version of blender - 2.40alpha2. Kept getting error ‘Eeekadoodle! An MFACE-EDGE! Tell Zr!!’ with old version of script, so methinks shifting sands of python API are shifting rather fast, lol.
New version also got a toon cog bit, obviously not a patch on BMG, but they do work with subsurf, and can look like this:
Only the subsurf bit of the api is changing so you have to do it manually at the moment, . Next update should bring the extrude along the line part which is what this script is hopefully all about.
