I created these RSS and XML badges for a project, and I was happy with how they turned out. I’ve seen bunch of tutorials on the web about how to create aqua-looking images, so I thought I would add this to the list. You can obtain the original layered Photoshop files here, for RSS and XML. They were saved in Photoshop CS2 with compatibility mode on, so they should open with past versions just as easily. Feel free to use them for whatever you want.
Update: By request: CSS (green) and xHTML (gray) badges as well.
