“Patricia Piccinini (born in 1965 in Freetown, Sierra Leone) is an Australian artist and hyperrealist sculptor. Her art work came to prominence in Australia in the late 1990s. Her major artworks often reflect her interests in issues such as bioethics, biotechnologies and the environment”. – Wikipedia

Chris Gilmour is one of those people that can turn unexpected things, which most of us would simply discard as trash, into astounding works of art. By taking simple cardboard packaging and other recycled items, he was able to create intricate replicates of various large items, paying close attention to even the smallest details. His cardboard sculptures include everything from vehicles (motorbikes, cars, bicycles) to religious symbols. Some people may find it sacrilege to create religious icons out of trash, which includes toothpaste, condoms, etc.; however, art should not be bound by prejudice and bigotry of close-minded individuals.

Born in 1958 in Kiev, Ukraine, artist Mark Khaisman studied Art and Architecture at the Moscow Architectural Institute in Russia. Now living in Philadelphia, USA, Khaisman uses rolls of brown packaging tape to create incredible works of art. Mark characterizes his work as ‘pictorial illusions formed by light and shadow’. The three key elements are: translucent packing tape, clear acrylic or film panels, and light. By superimposing layers of packaging tape Mark can ‘play on degrees of opacity that produces transparencies highlighted by the color, shading, and embossment’.
