I’m happy if someone with artistic skill wants to contribute alternatives. The icon/logo was meant to be good as an icon at the 16x16 and 20x20 pixel sizes. I think it’s the best program icon, but there’s room for improvement at larger sizes for a graphic for use on websites.
It’ll be a lot simpler if authors could make their graphics public domain.
Thanks for clearing up the issue on public domain . Now I can release the graphics I have done into public domain.
