In a complete reversal of the usual conventions of painting, UK artist Boo Ritson actually paints on her subjects - carefully styled models are liberally coated in standard household emulsion, and the results then photographed.
Vacillating curiously between cartoon-like representation and intense character study, her work provides an amusing subversion of standard depictive process as well as a celebration of the gloriously gooey qualities of paint.
New York artist Dan Colen is known for unconventional art tactics, and his bubblegum paintings certainly seem to fit that bill (although Paul Mccarthy's gum prints 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.
Swedish artist Henrik Håkansson, who has also produced a recent series of poop pics, has no such scruples, enlisting the aid of passing swallows to really and truly splatter his canvases - a gesture, we should add, that's entirely in keeping with Håkansson's nature-based art.
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.
UK artist Gavin Turk, having previously appropriated Warhol's screenprints and diamond dust finishes, recently embarked on his own series of pee paintings (left).
Whether, like Warhol, he was on hand to witness invited assemblies of attractive young men producing each work is not entirely clear.
In what must be the most unusual take on an ice sculpture ever, fast emerging UK artist Katie Paterson'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.
