Update (June 2008): Archlinux has a new logo since December 2007, but you might also want to see archminimalist.
I’ve been working on an alternative logo for Arch Linux. It’s not that the existing logo is terrible…but it reminds me far too much of Star Trek, and, in my opinion, it doesn’t render well when converted to one colour. Released under a Creative Commons license, you are free to use and modify the logo to your liking, so long as you credit me (Thayer Williams) as the original artist.
