Sam Palmer is not a choreographer, but he plays one at the public library in Fayetteville, Arkansas. From his basement office, Palmer has created a dance for the building's interior lights on his computer system, giving each a role for different times of day. Some dim on bright days. Others turn on as staff members arrive. In the late afternoon, half of the lights turn off.
Ann Arbor, Michigan, also relies on sophisticated computer programming to light its city buildings and conduct some intriguing experiments with outdoor lighting.

Now, energy officials are taking control of 28 of them and using radios to dim them, make them flash, or turn off one or more of the four lighting panels in each streetlight.
