Education is a life-long process. We choose individually how much we want to invest in it. If you are interested in studying a new subject matter all you have to do is search the internet. But at a point just browsing around isn't enough and you may want to pursue something more formal.
If a full-time or multi-year degree program isn't for you, consider putting together a number of smaller programs and experiences to complete your education. By combining many different programs you can tailor the education to your interests and avoid studying topics you're not interested in.
This is a living document that is intended to act as a course catalog for those interested in constructing their own education at the intersection of the arts and technology.
