THE MOST UNUSUAL CONTEMPORARY ART WORKS
New York artist Dan Colen is known for unconventional art tactics, and his bubblegum paintings certainly seem to fit that bill (although Paul Mc Carthy's gum print go just that little bit further by actually being edible).
Less obviously palatable are Colen's 'bird poo' pictures, which seem to have been authored by a super-sized colony of pigeons.
In fact, they're produced in oils, so although we can salute Colen's trompe l'oeil abilities, he's less hands-on than we imagined - or simply mindful of buyers' delicate dispositions.
US artist Fiore's brightly coloured abstract works could justifiably be termed 'explosive' - they're created using the smoke and residue left by fireworks and other combustibles carefully lit over paper.
While Chinese artist Cai Guo Qiang is well-known for creating works using similar techniques, Fiore's practice is far less random, her effects carefully controlled by guiding her unusual pigments across her composition - at a safe arm's length, naturally.
From bodily wastes of a (fairly) solid variety we turn, inevitably, to the subject of pee as an artistic medium.
Urine was (probably) first used as a medium for painting by Andy Warhol in 1961, and although only a photograph exists of that particular work, the Pop master again took up the general theme in the mid 1970s.
Rather more ambitiously, the so-called 'oxidation paintings' depended on the chemical reaction of urine with copper paint.
In what must be the most unusual take on an ice sculpture ever, fast emerging UK Artist Katie Petersonn's ice LPs form part of a work chronicling the life of glaciers. The artist first recorded the sound of the melting ice-stacks, then had these 'tracks' cut onto discs created from the meltwater itself. To complete the cycle, the ersatz LPs were then played on turntables until the ice once again melted. Genius.
