About the Author
Michel Anders, after his chemistry and physics studies where he spent more time on
computer simulations than on real world experiments, the author found his real interests
lay with IT and Internet technology, and worked as an IT manager for several different
companies, including an Internet provider, a hospital, and a software development company.
After his initial exposure to Python as the built-in scripting language of Blender, the popular
3D modeling and rendering suite, the language became his tool of choice for many projects.
He lives happily in a small converted farm, with his partner, three cats, and twelve goats.
This tranquil environment proved to be ideally suited to writing his first book, Blender 2.49
Scripting (Packt Publishing, 978-1-849510-40-0).
He loves to help people with Blender and Python-related questions and may be contacted as
'varkenvarken' at http://www.blenderartists.org/ and maintains a blog on Python-
specific subjects at http://michelanders.blogspot.com/.
For Clementine, always.
