'Nature's Energy' by Promethium, CarDim and the Wastelander is a fascinating art series that captures power sources in a forest. By placing light bulbs in various spots, the artists illustrate how Mother Nature generates energy through decomposition and symbiotic plant life.

The final two images in the gallery above are titled 'Urban Mushrooms.' An opened clear umbrella makes the symbolism clear. See more shots from 'Nature's Energy' by Promethium, CarDim and the Wastelander above.
