|I was fooling around the other day and did this, having no idea how much it would inspire me to action. All I did was save a picture of the pattern illustration as my desktop background. This is very easy to do, and to change.
I plan to do this, changing the pattern picture as I work on different projects. I find it makes me more likely to find time to work on my project. A new definition of "nag screen."
I'm sure it is easy on non-Windows systems, but I can't tell you how to do it there. On Windows, surf to a nice big picture on the online pattern catalog, put your cursor over the picture, right click. You'll have a list of optional actions, including one like "set as desktop background" or "set as background".
If you decide you hate the change, right click on your desktop, find Properties (or Desktop Properties) and Background.
