I stumbled across and amazing free ebook recently- DroidMaker (the link takes you to the authors blog, where he's release the PDFs). The story is an amazingly detailed history of the formation of Lucasfilm and the evolution of what became Pixar. I done some 3D modeling and rendering in the past (using Lightwave) and it's amazing to realize that these guys literally had to invent and write this stuff as they went along.

I was initially trying to convert the PDF to an ebook for reading on the iPhone, but found that nothing will convert a PDF nicely-- but that is for another post. What I did find is that the MacAir itself is a really nice ebook reader if you rotate the PDF to the right using Preview, and then hold the Air open on your lap like a book. It's small, light and thin enough that it really makes a great reader.
