When KDE 4.2 was released, the team issued a new wallpaper called Air, or something along those lines. This is my version of it. I know that there are a ton of Bokeh type wallpapers floating all over the internet, but I wanted to bring one more to the table.
This is a wallpaper pack of sorts. Included in this pack are 4 different wallpapers: 2 for wide screen (2560x1600) and 2 for standard screen (1600x1200).
Of course these are for the Mint versions of Gnome and KDE.
