A client needed to visualize the regulatory uncertainty in his industry after the financial crisis. This traffic light tree in London is a very useful art installation that you can use in many other confusing situations. The high rises of large financial services firms in the back help complete the picture (my client works in that industry).
The Internet is full of images of the sculpture. Try searching Flickr for images with a Creative Commons license.
