In the summer of 2004 I received a call for logo proposals from the Free Software Foundation Europe. I did this as an ambigramm, with little asymmetric additions.
Although this logo was a) not accepted and b) admittedly not very well fit for the purpose (it would do better as a general FSF logo, but I wont be napoleonic here ;-) I like it enough to publish it here.
I did this in real Postscript and must admit that the experience of writing a graphical programm in XEmacs and then see the outcome in an automatically updating GV was quite interesting.
