When you stare at the same screen for hours and hours, it’s important to have good desktop wallpaper. “Good” can mean useful wallpaper- as in the case of developer cheat-sheets or calendars- or inspiring wallpaper, that can motivate you or give you ideas for your current project.

Here are 25 of my favorite desktop wallpapers, all available for free download. If nothing else, I urge you to scroll down to see the last one, currently my desktop wallpaper on my workstation.
