Smears, Multiples and Other Animation Gimmicks
The geekiest, and therefore coolest, animation-related Tumblr I’ve seen: Smears, Multiples and Other Animation Gimmicks. Tumblr users are invited to submit their own examples of these animation ideas. The blog is run by Michael Ruocco, a promising recent grad of the School of Visual Arts whose knowledge of classic animation is second to none.
(Disclosure: Michael did some work for Cartoon Brew last year and has also assisted me on some of my recent book projects.)
