Sometimes a single picture can change the course of history, and it might be happening again in Iran.
This time it is a cellphone picture, and what it shows is a teenage girl dying at the hands of the security forces.
Its impact through the internet may just topple a president.
Sixteen-year-old Naida was an innocent bystander to the protests. She was shot dead by security forces, and her last moments- caught on a cellphone camera - have become the face of a protest movement, sent all over the world.
This evening it was protesters in Wellington knowing and speaking of what her brutal killing represents. A gagged youth represented a generation under repression and a country's media banned from telling the real story.
"That's really what we're here about today," says Julia Wells. "People's right to freedom of speech and freedom of political expression."
The death of Naida has sparked a sense among Iran's protestors that there is now no going back.
But as opponents of Iranian president Mahmoud Ahmadinejad grow committed to an uprising, his own security force is standing steadfast.
In another sign of a colossal power struggle, a previsouly untouchable figure - the daughter of Ayatollah Rafsanjani - was detained overnight. Rafsanjani is the most powerful supporter of opposition candidate Mir Hossein Mousavi, and while his daughter was released, scores of other human rights activists, bloggers and journalists remain in detention.
Messages on social networking site Twitter are another horrifying insight into the situation. Protesters are being urged to give blood if they are too scared to go out on the streets, and use CB radios for communication so they cannot be tracked.
Through a statement, Mousavi has urged more protests and planned massive strikes.
"Protesting against lies and fraud is your right," he says. "Today the country mourns for those killed...remain calm."
But today's developments suggest calm is exactly what this country won't see for a long time to come.
Ahmadinejad's message to a group of clerics today did not reflect the violence on the streets. He said the election had proved the Iranian people's love for the regime.
