I'm an amateur graphic designer, with a decent head for theory, and intermediate skills. I would like to run a graphic design course for my friends, but I would prefer not to spend months on developing the course. I recently ran a workshop on using git, and for that I used someone else's open source git tutorial, which I modified, and expanded. I would love to be able to do the same with a graphic design course (ideally, a short series of workshops).
Is anyone aware of such a course? e.g. a set of editable slides, or a course outline/framework, that is available under an open source license (creative commons, GFDL, etc.)?
There are plenty of courses available on youtube, but for the most part, they aren't available under an open license, so I can't re-use the content. There is also the wikibooks graphic design book, but it's pretty empty, and also not really in a suitable format.
