This is really more political than religious, but Nolnet's Go Iran supports the protesters in Iran, who have been wearing green, a color associated with Mousavi's campaign. The reason to put it on this blog comes from the questions, why green? Green has been associated with Islam since its inception. Surah 18:31 of the Quran says of those in paradise that "For them will be Gardens of Eternity; beneath them rivers will flow; they will be adorned therein with bracelets of gold, and they will wear green garments of fine silk and heavy brocade." Greenery represented paradise to a desert people. It is said that Muhammad wore green and had a green banner, and green has been used in mosques, the graves of saints, covers of the Quran and the flags of Islamic nations. So in choosing green as their color, protesters are both linking with Mousavi and with their religious roots.
