Graphics, Media and everything else on this page is, if not marked as citation, available under

CC BY-SA 3.0

You are therefore free to use, modify, distribute or copy all material under this licence, for personal and commercial use. If the material is not made by the owner of this site, a citation is always used (square brackets like [4]) in the image description.

I can provide the original vector images if needed.

You must give appropriate credit, for example by using citation methods or when using on presentation, write the label “Hartrusion” in a small font next to the image. The note doesn’t need to be put like an advertisement, it should just allow any interested person to see where the graphics are from.
