These are a few chess piece sets that I have created in my spare time. They were created using Inkscape. You can find both the source SVG files in a a unique archive, the processed PNG files (with and without shadow), and a theme for XBoard.
If you are writing a chess program you are welcome to use my themes, provided that you give me credit in a suitable way. I will als be happy if you notify me by e-mail.
Here is archive containing all [SVG files]. For the PNG images and the XBoard themes you can download the image packs here:
