Note: The above is just an image capture. You can view the video by clicking here.As I reported here and there on the Art & Story podcast in episodes back in July of 2008, last year I led a 6-week cartooning workshop for teens at the Ann Arbor District Library. I was videotaped during the formal presentation every week, and the library has since collected the series as a video podcast called "Comic Book Academy".
You can watch the first video here. The running time is 38 minutes, and there you can download a high-res version as well as an iPhone-ready version, or even an audio-only version.
The rest of the episodes, covering world-building to penciling to inking, will be released on the Ann Arbor District Library Website soon.
