If you don't know about Mike Nguyen's animation blog RAINPLACE , then get it on your bookmarks list and visit regularly. Mike has some of the most detailed and thoughtful pieces on the nuts & bolts of animating that you will find on the internet ---
Recent topics included : Fielding a Scene (the effect of field size on the perception of an action) , Amount of Extremes to use when animating a scene, Phrasing , Squash & Stretch Applications.
Great stuff ! This is one of a handful of blogs that I would gladly pay a monthly subscription fee to view. However, Mike is such a generous , giving spirit that he is giving it away for free. (seriously, Mike you should at least put up a PayPal "tip jar" for those who would like to contribute to support your efforts)
In case you don't know , Mike is directing and animating an independent , self-funded feature length animated movie "My Little World".
