Democracy activists in Hong Kong are preparing to mark the first anniversary of the ''umbrella movement''- when tens of thousands of people paralysed key parts of the city, calling for greater democracy.
Their demands were not met, but the protest inspired a creative outpouring on an industrial scale.
As the BBC's Juliana Liu reports, some of the protest art has been preserved.
