Would you mind to provide a license? I'd like to include these assets into an open hardware project of mine. They'll be distributed both in a converted form and as images, but I'd like to provide a specific license anyway.
It might be Creative Commons Public Domain or New BSD License (3-clause BSD License). Personally, I'd prefer the second one because it allows me to include your work into my project, but protects your copyright from being used in promotions.
