Scottish artist Rob Mulholland has given the world unique works of art, which is a mirrored sculpture, almost invisible against the background of green foliage of the Queen Elizabeth forest Park, in the city of Aberfoyle.
Six human figures in natural size, carved from translucent acrylic plexiglass, tend to suddenly disappear or appear depending on the location of the observer. The ghostly silhouettes of sculptures the artist had copied from their friends and acquaintances. The artist, via his website:

The essence of who we are as individuals in relationship to others and our given environment forms a strong aspect of my artistic practise. In Vestige I wanted to explore this relationship further by creating a group, a community within the protective elements of the woods, reflecting the past inhabitants of the space.The six male and female figures represent a vestige, a faint trace of the past people and communities that once occupied and lived in this space. The figures absorb their environment, reflecting in their surface the daily changes of life in the forest. They create a visual notion of non – space. A void as if they are at one moment part of our world and then as they fade into the forest they become an intangible outline“.
