That Greek nazi party symbol comes from the sign used for the israel shekel http://en.wikipedia.org/wiki/Shekel_sign I am surprised that im the only one that noticed it.
Though the Greek nazis claim it comes from Greek Meander art:
Allegations of Nazism
The party is regularly described as Neo-Nazi by the international news media, and members are allegedly responsible for anti-semitic graffiti. Officially denying that it has any connection to Neo-Nazism, the party maintains that it cleaves closer to the authoritarian nationalism of Ioannis Metaxas, the Greek general who established the 4th of August regime, in Greece between 1936 and 1941.
In a 1987 article of the Golden Dawn magazine, its editor Michaloliakos wrote an article with title "Hitler for 1000 years" where he supports Nazism and white supremacy. Specifically he wrote "We are the faithful soldiers of the National Socialist idea and nothing else" and "[...] WE EXIST, and continue the battle, the battle for the final victory of our race". He ends the article by writing "1987, 42 years later, with our thought and soul given to the last great battle, with our thought and soul given to the black and red banners, with our thought and soul given to the memory of our great Leader, we raise our right hand up, we salute the Sun and with the courage, that is compelled by our military honor and our National Socialist duty we shout full of passion, faith to the future and our visions: HEIL HITLER!". Furthermore he capitalizes the pronouns referring to Hitler ("by Himself", "His people").
Party founder Nikos Michaloliakos appeared to give a Nazi salute in the Athens city council. He claims that it was merely "the salute of the national youth organisation of Ioannis Metaxas". The party states its logo is a traditional Greek meander, not a Nazi symbol.
In May 2012, Golden Dawn ran in Greek elections under the slogan "So we can rid this land of filth". On his post-election statement, leader Nikos Michaloliakos had placed a marble eagle, on an obvious position on his desk, which according to media reports bears similarity to the eagle of the Nazi Third Reich. Post elections, Golden Dawn's MP Eleni Zaroulia wore an iron cross ring during her inauguration, a symbol which has been associated with Nazism.
On July 23, 2012, Golden Dawn member Artemis Matthaiopoulos was elected MP for the town of Serres. The website left.gr (associated with SYRIZA), reported that Matthaiopoulos was the frontman of the Nazi punk band "Pogrom" and pointed to the band's song "Auschwitz" with antisemitic lyrics such as "fuck Anne Frank" and "Juden raus".
A meander or meandros is a decorative border constructed from a continuous line, shaped into a repeated motif. Such a design is also called the Greek fret or Greek key design, although these are modern designations.
