GNOME Turns 18 Years Old Today
The birthday reminder via GNOME.org. It was on this day in 1997 that GNOME was announced by Miguel de Icaza and Federico Mena.
Another ~2005 pic of GNOME. Unfortunately I don't have any pre-2004 screenshots of GNOME that are original by me due to having started Phoronix in 2004.
For those that weren't into open-source back then, you can read the original GNOME announcement still on the mailing list.
