John Canemaker has been contributing articles to Print's online version. His latest is "Chuck Jones at the MacDowell Colony," a speech that Canemaker made as the prelude to Chuck Jones receiving the MacDowell Medal. Jones was only the second filmmaker to receive it (the first was experimental filmmaker Stan Brakhage).
You may have seen video of Pixar's three dimensional zoetrope. If not, you can see it here. Gregory Barsamian is a sculptor who does something similar, creating sequential sculptures that he then films using strobe lights. Unfortunately, his site does not allow embedding or direct links to specific pages, but you can see his work here.
Hogan's Alley is an eclectic magazine about all forms of cartooning. The 17th issue is out and the articles relating to animation include a career-spanning interview with the late Bill Scott conducted by Jim Korkis. Scott was a writer for Warner Bros, UPA and most especially, Jay Ward. There is also an oral history of Spongebob Squarepants. Hogan's Alley has an absolutely horrible web presence, but you can see some web extras for this issue here. You can subscribe here, or look for the issue at better comics shops. If you're going to subscribe, be aware that the magazine appears just annually.
