I've been teaching computer graphics for about 14 years now, and I absolutely love my job. I feel like they pay me to be creative -- and to show students how to unleash their own creativity. Most of the projects I submit are examples of projects I am teaching in my classes... although when I am inspired by a submission I see on deviantART I sometimes play with it [with the deviant's permission].
I also have my students sign up for deviantART pages to serve as digital portfolios. They are surprised by the positive feedback and love they receive by the DA community.
