LED traffic sign in Texas displays witty warnings of global warming

While some who saw this variable message sign in Houston though it had been hacked, it's actually a roadside art installation by Brooklyn artist Justin Brice Guariglia.

The words come from Rice University professor Timothy Morton, author of Dark Ecology: For a Logic of Future Coexistence. The solar-powered sign, located at the Gus S. Wortham Memorial Fountain, will be displayed through August.
