Not sure if this is the right category, but JoomlaBamboo templates usually got pretty cool backgrounds. Not too complex, yet stylish. Will you share some of your sources? Or this is something you create yourself.

This is also a question to anyone who is vieweing. If you have some good resources for backgrounds to use on web sites, please share.

Hey Dimitry,

Depends on the theme but we make them ourselves although we often mix and match textures etc that are available about there. Id highly recommend checking out graphicriver.net as a good source of elements to work into a design.
