I saw this really brilliant logo posted by 'sailor' on fedoraforum.org
I don't remember seeing on the mailing list, so I uploaded it onto my
site, and changed the size into all the standard icon sizes.
If i get a vote, this one has it
Sailor has done an amazing touch up of the origninal 'infinite freedom' idea

The icons do get a bit grainy after we shrink them past 64x64, but I think that with a bit of touching up, this can be fixed.
