One nice feature on Chess.com is that you can change its default appearance by selecting a theme suited to your taste. Some are provided by the webmaster (Standard Chess.com Themes), but with everyone free to create at least one theme, the majority is member-made.*
I have been a member of Chess.com since early 2008, and I also happen to be active in graphic design. It should therefore be no surprise that I gave it a shot, and created a theme of my own ("Metal Chess"). This one is now used by quite a lot of people, and I'm happy about that as it is always nice to share.
Recently I decided it was time to expand my collection of themes, and after putting in the time I came up with some new themes. I have showcased them below .
