I've also posted my first tutorial. It details the steps neccessary to create a piston in 3DS Max 7 using a history independent inverse kinematic setup.
This type of setup is useful if you're planning on creating any type of machinery that involves hydraulics like bulldozers, loaders, coal and garbage trucks, etc.
I plan on posting more tutorials eventually.
The next one will probably be about digital ink and paint techniques in Photoshop.
