[opensuse-artwork] Off topic - visual metaphor for 'free software'

Dear all, I apologize for using this list to ask a question, but given the fact that artists populate this grounds, I consider this might be a cool place to shop for this information. Generally speaking about 'Free Software', what would you suggest as an icon/logo to provide a visual metaphor for 'Free Software' ? Why I ask this... well, for a project I'm working to create a tiny information channel in Portuguese (since we lack them).
