shadow chalking

Shadow Chalking is chalking an outline or halo around shadows cast by street lights or other stationary light sources.
Shadowchalking started in Berkeley California by Dan and the phrase was coined by Leonora Bittleston (flio).
One significant aspect of shadow chalking is that it is an approach to transforming the light to construct optical riddles. Shadow chalking can be as simple as an outline around a shadow, or it can use shadows as jumping off points for more complex ideas. At its heart it is a public call to prompt closer observation of light and draw attention to the urban landscape and to bring awareness to our changing relationship to objects and environments in different lighting contexts. Shadowchalking can also be an approach to street art that incorporates the use of shadows as formalizing elements.
