The recycled fan guards used to create "What Lies Beneath" by Nicole De Mestre is the artist’s comment on the ubiquitous and inexpensive cooling fan, often dumped on roadsides in Australia. The resources depleted to create the mass-produced fans end up as landfill, thereby adding to the ever-increasing layers that lie beneath.
Garden lime, essential to remedy acidic soil, is made from pulverized limestone or chalk. Limestone is formed from the calcified skeletons of countless tiny single-celled algae, deposited on ancient seabeds millions of years ago. The microscopic remains of these organisms bear an uncanny resemblance to discarded fan guards.
