We should have a section or this topic, where designers can post and the rest of us can download wallpapers with CodeIgniter, Codeigniter logo, stickers and other stuff like that.

CodeIgniter could also have a store, where all the profit should go in growing CodeIgniter or should be donated to a charity project.

We have a repository intended for such things, https://github.com/bcit-ci/ci-design

It is very much a work in progress, and needs some re-organization.
The forum and user guide styles need to be packaged for adding to it.
The website style will be removed, as the website itself has been open-sourced.
The smilies will be removed too, as they are deprecated and not needed/relevant.

I will work on that, and add some categories along the lines you suggest, over the Christmas break.
We can then let members of the community propose material to be added

A CodeIgniter store doesn't make sense to me - we don't have anything to sell, not are we soliciting donations for anything.
