The original commercial is even better than the parody they keep making about it.
Here is the newest by DreamWorks :)
During the last year, I had the privileged of reading, remarking, and in the end even be in charge of the graphic design of this wonderful book "The Mechanics of Inspiration" which was written by a good friend and collegue of mine - Doron Meir.
This book takes us through the creative process from the beginning - the idea it self, until the final product, no matter if it's animation, a piece of music, a sculpture of any other creative work.
The book itself is written in Hebrew but I highly recommend it and you are more than welcome to check out his blog regrading his book.
I hope you'll enjoy it as I have.
