I know some people can't afford Photoshop and such to create/edit textures, splash screens, huds, menu's and so on.
I do create all of my pictures and so on with the tools from Serif. They're very affordable and powerfull, I've bought almost all of their latest versions.
BUT, you can get their tools (some older but good working versions) for FREE here:

There you'll find some very helpfull free tools for FPSC:

* DrawPlus 4.0 - Graphic Design and Vector Drawing. Good for working on splash-screens and such
* 3DPlus 2.0 - 3D Animation and Modeling. Excellent for creating 3D text effects for your menu texts
