A friend of mine attended a sakuga panel at ACen, and once the panel got hosted on YouTube, he linked it on Twitter. I finally got around to watching it yesterday, and as someone who is embarrassingly ignorant about this sort of thing, I found it a compelling watch. I think every fan of animation -- not just anime, but animation in general -- should watch and learn from this. It's quite interesting. The videos are also split into nine easily digested parts if you don't have time to watch them all in one go.

Just to define: Sakuga is basically a single animator leaving a defining mark on a scene or show in general (as is the case with someone like Hiroyuki Imaishi, whose style is recognizable across Diebuster, Dead Leaves, Gurren Lagann and Panty and Stocking with Garterbelt). The sheer variety of touches and styles is remarkable, and definitely gives me a better appreciation of the medium, especially as someone who tends to pay a bit more attention to the writing and characterization side of things.
