If, like me, you arrived too late for Oregon State University's May course, they're running it again. Yippee!

DESCRIPTION
In this free, online course, you’ll learn about the process, ethics, and principles of
permaculture while diving into climate-specific design elements through interactive technology, videos, graphics, and readings.
Permaculture design is a method of landscape planning that can be applied to anything, from a home garden or farm to a
city block or entire village.
Permaculture uses design principles from nature itself and takes into account such things as how indigenous people used the
land. This course is designed to benefit everyone regardless of learning style, time commitments, or available technology. Expect to spend between two to four hours each week on coursework.
