New York Times:

Words appeared in the sky, the color of clouds, and then faded into a jumble of letters in the background. It was an ephemeral poem, with lines like “Catch the falling knife” visible for a few seconds through the portal of an iPhone pointed at the skyline above Central Park.

The walking tours will be free and open to the public starting on Saturday, and in addition to New York, will be offered in San Francisco, London, Paris, Hong Kong and Tokyo. Each starts from an Apple Store and features the same set of works. The pieces are only accessible at specific locations on the walk, making them installations of a sort, in an open-air, virtually accessible exhibit.

I’d love to see this. If any of you are lucky enough to live in one of the featured cities, please let me know what the experience was like!
