Of late I have bemoaned the fact that several important blogs of the past have shuttered or closed. Often this is due to the considerable work schedules of the authors and (thankfully much more rare) the death or ill health of the blogger.
There are occasionally new blogs that appear that delve deeply into the world of animation and renew that spark of life experienced in those other wonderful blogs. Here’s a really nice one by James “JC” Chiang:

His most recent article explores the work of Milt Kalh:

I love the overlap of shapes that Milt brings to his work that creates 3D space within the realm of a 2D plane (in this case specifically for viewing on a movie screen).
Best of luck in the endeavor James!
