Towards Blender 2.55

I had a little break from Blender but now its time to go back and see what devs have been doing. I just converted my old pyramidaze script for 2.55. It is REALLY simple but it was my first python script back in 2006 :)

It just iterates through selected faces of the object and adds a pyramid top of them (see image above).

Here is 2.55 version:

#**********************************************************************************************
#pyramidaze.py
# - This script adds a "pyramid" over every selected face
#
# - Open this file in the Blender's text window
# - Select faces
# - set settings (see below)
# - run script (Alt + P)
# 
# there is nothing special in this script but it shows how to iterate 
# through all faces in selected object, how to get normal and how to 
create new mesh object.
#
# Feel free to use this script any way you like, I'm sure this is very useful ;)
