My friend Peter Macleod has a great idea in a comment piece in the Toronto Star today. He suggests that the new LED lighting system on the CN Tower should be used to show the city the impacts of citizens’ collective behaviour:

A nighttime glance at the tower could tell us whether we were gradually rolling back car usage or whether it was continuing to spike. It could tell us whether power consumption was in hand or we were headed for a brownout. Most importantly, it could illuminate our public imagination – to remind us of our goals and the progress we want to make.
