Iranians across the world found ways to have their say in the country's presidential election. One initiative which resonated across the globe was an online comic strip. The main character is Zahra – a mother whose son disappeared during the 2009 presidential election protests known as the Green Revolution. Zahra has been running a fictitious presidential campaign built around a platform of human rights and greater democracy. And she's been getting some support – with people posting pictures of themselves with her image on the "Vote for Zahra" website. Zain Verjee spoke to the character's creator, Iranian-American journalist Amir Soltani.
