This was for a show at Worksound Gallery entitled "Ask The Lonely". A wall drawing with a shadow on the floor consisting of roughly 6,000 dead flies.
The shape of a skeleton was affixed to newsprint and the newsprint was left in a window for a month. The resulting sun and water damage to the paper made the shape visible.
This was a performance and installation for a month long art show/performance space/event. Several thousand matchsticks were stamped by hand with this advice and then left out for others to act on. Allowing a match to burn down slightly will change the advice given.
