After watching a presentation at my college, Rochester Institute of Technology, by Lawrence Lessig, founder of the Creative Commons, I’ve decided to license all my artwork under a Creative Commons license.
I’ve licensed all my artwork (in my gallery) under a Creative Commons Attribution-Noncommercial-Share Alike 3.0 United States License.
I think that everyone should do this to at least some of their work. It helps people avoid copyright problems and helps promote the sharing of information.
