I recently come across this website http://lesterbanks.com/ that does a lot of useful and amazing tutorials for loads of major 3D packages and compositing software.
They even have an online store where you can order hilarious CG and geeky software related taglines that only fellow geeks can understand.
I really wish I had the time to go through all the tutorials. I am just browsing and I am already seeing very useful tutorials that I would like to watch NOW! But... my wife is in London for holiday and I'm loaded with things to prepare for my return trip back home to Singapore.
