To me, Che Guevarra is a hero. The famous 1960 picture of him is a prominent symbol of rebellion. I think, however, that people display the picture simply as a sign of any kind of rebellious attitude without any real reference to the actual man. But I feel more kinship to him than your average teenager who simply wants another role model in simplistic anti-establishmentism.
Che followed his beliefs in freedom, embodying the good that Communism is really supposed to represent. The GNU/Linux community also holds a place in my heart and my personal philosophy. I feel strongly in freedom and the power of the individual, and I hope you get some small satisfaction out of this mash up.
I didn't create all of this from scratch, (And I wasn't the first one to come up with this idea either, but I did everything myself)
