Our many lives are fleeting, like clouds in the sky.

Enjoy a magnificent visual metaphor for this idea, a time-lapse piece by artist ken Murphy called A History of the Sky… (“Long Shorts” are short films that exemplify long-term thinking.  You can find more of them on the Long Now Blog.)

“Art project in progress A History of the Sky features lots and lots of time-lapse videos of the sky that are synchronized so that they’re all showing the same time of day.  Ken Murphy is the artist that created it and he hopes to one day manifest all the data he’s collecting as a video installation that’s always displaying the skies of the last 365 days.  The project was recently featured at the Exploratorium, but it’s still in a need of a home for the installation.”
