Word of the Day - Extrude

On Monday I downloaded a freeware modelling program, Blender. I googled lot of different programs, but decided to try this one out. And so far, I'm loving it :) It's completely different to model in 3D than to draw with normal 2D. But I've started to study this program with a youtube clips, and so far I like CGBoorman's videos the most. Now I'm at the point that I've started to create an elf''s head...vov.
