In 2006 Marius Morawski did some quality artwork for Gentoo: a logo for Gentoo/FreeBSD and two related wallpapers. His work is licensed under GPL version 2 and available through the Gentoo website finally.

Credits for the non-trivial task of re-shaping the dark skies wallpaper to aspect ratios of 4:3, 5:4 and 8:5 go to Matteo 'Peach' Pescarin.
