I'm a Windows user. Both laptops in this house are Windows. I have nothing against Macs; I just don't have any in this house. And while I am playing with Linux for experience sake, I doubt I'll be programming for it.

That said, all of the wallpapers should work as wallpapers on other OSes. However, many were designed to have the Windows 95 taskbar at the bottom of the screen, so they don't quite fit Mac's taskbar at the top or even the Gnome interface for Linux with bars at top and  bottom.

Any future wallpapers will be "OS Neutral".
