This striking Volumen series of sculptures/paintings is by Swiss artist Fabian Oefner. He has somehow captured two-dimensional brushstrokes in three glorious dimensions, forever freezing them within a block of resin.

"I have always been fascinated by the textural quality of paintings," says Oefner. "For me, experiencing works like de Kooning's Door to the River or Pollock's Lavender Mist has always been as much a tactile experience as a visual one. These paintings are almost like sculptures to me. What I am doing is removing the canvas entirely and lifting the paint into space, making its physicality completely tangible."

If I had to guess, he paints onto a strip of acetate or similar, waits for it to dry, then suspends it within the resin before it cures. Any other ideas?
