The Big Easel, Emerald, Central Queensland: The Big Easel installation art piece, created by Canadian artist, Cameron Cross, is located in the town of Emerald in Central Queensland, Australia.  Erected in 1999, and unveiled in October of the same year, the installation artwork depicts Dutch artist, Vincent van Gogh’s (1853-1890), famous "Sunflowers" (1889) still life painting, which is currently part of the Van Gogh Museum’s collection in Amsterdam.  The monumental reproduction of van Gogh’s painting is located on the corner of Dundas Street and the Capricorn Highway, situated in the centre of Emerald’s Discovery Park.  Weighing approximately 17,000 kilograms, Cross’ steel easel measures 25 metres in height, with the canvas measuring 7 x 10 metres.  The easel’s three legs consist of 30 x 30 square centimetres of steel tubing, which are secured to 10 metre piers by 24-1 metre anchor bolts.  To recreate van Gogh’s canvas, Cross has used twenty-four sheets of plywood, laminated together from four panels, each of which is coated with fibreglass and then sealed with a gel coat.  The plywood canvas is painted while flat on the ground, using high performance paint, which is both sprayed and hand-painted onto the surface of the plywood.

"A Subtlety" was dominated by its central piece, a white sculpture depicting a woman with African features in the shape of a sphinx, but also included fifteen other sculptures.

Robotic art: Robotic art is any artwork that employs some form of robotic or automated technology.  There are many branches of robotic art, one of which is robotic installation art, a type of installation art that is programmed to respond to viewer interactions, by means of computers, sensors and actuators.  The future behavior of such installations can therefore be altered by input from either the artist or the participant, which differentiates these artworks from other types of kinetic art.

Edward Łazikowski: Edward Łazikowski (born January 22, 1939, in Bąków Górny Poland) is a Polish artist whose work includes drawing, painting, photography, sculpture, installation art, performance art and art theory.  Łazikowski graduated from the Strzemiński Academy of Fine Arts and Design in Łódź.  He presents his artistic and theoretical achievements publicy in individual exhibitions and taking part in collective shows in galleries and museums, poblishing catalogues and articles in various magazines, and giving interview.  Initially, he went in for painting (in the 1960s), then in the mid-1970s took interest in "actions" and photography (mainly documentary), and in the late 1970s and early 1980s performance art.  Later on he created "objects" (sculptures): small constructions made of wood, string and fabric, which in time became larger, and sometimes became installations.  An important part of his creative process is drawing, divided by the artist into three categories: free, working and note.  Starting from the 1990s, he introduced a series of works called Fragtors.  The term, coined by Łazikowski, and precisely described in his theoretical work "Fragtoryzacja świata" ("Fragtorisation of the World"), became the basis for artist's present plastic activities.  In his theoretical and constructive works Łazikowski tries to combine discovering reality (science) with creating it (art).  Łazikowski describes his aim as to carry out the "spiritualisation of his corporality (but not of the corpse), and corporalisation of his spirituality (but not of the spirit)."  He sometimes exhibits his works outside galleries, at places unrelated to arts, not promoted by media and advertising campaigns; often outside the "field" of art.
