I think the HURD logo is actually quite good. They should use a different typeface though. And you can't really complain about the MIT Scheme one, that's exactly what it is :) (although it too could benefit from a nicer typeface for the Y combinator equation). GNU Parallel has a great idea but also, I think, needs a better typeface. But the recutils one... WTF!?
