Invisible Ink

The pages are still blank, but there is a miraculous feeling of the words being there, written in invisible ink and clamoring to become visible. ~Vladimir Nabakov about writing

I was walking along the streets of Beijing when I saw a quiet group of people dipping their big brushes into icy water to write calligraphy on the pavement. Poems, quotes, words or even a simple character would briefly resist natural laws before they evaporate. Calligraphers, as it seems, remain inspired and fulfilled - otherwise they wouldn't be there every day.
