Brian : yes they are on the developer section on the website : http://openbossa.indt.org.br/canola/developer.html

- on the bottom : for "Theme makers" design sheet.

you actually have the PSD (photoshop file) already "sliced" and named, so you can simply change the graphics there, and export / slice inside photoshop with ease.

Then, we are doing the webservice that compiles, and give you a debian package with your theme, you just need to upload a zip file with your files (there's one slightly issue that you should create some folders before generating the zip)

So you don't have to unpack
