Just came across "Show me do", a website that contains a wealth of tutorials about programming. All the videos can be downloaded at no charge, and they form a wonderful introduction to computer programming. I wanted to learn Blender for quite some time now, and this series of lectures look perfect for a beginner like me.
Show me do also has great Python tutorials. Python is probably the best introductory language: perfect for kids and adults alike. It works on every computer, and is free to download and use. Give it a shot!
