All subscribers of the gnupg-users and gnupg-devel mailing list had the chance to vote on the new logo of GnuPG.
I had used this chance too, and am very pleased with its result.
You still got the chance to donate some money to the winner, though!
I think GnuPG is a very important piece of software, concerning Freedom as well as Privacy and having a modern logo which represents both is really necessary.
UPDATE: Link corrected, thanks Stefano!
