Art and design duo the Haas Brothers has revealed a series of otherworldly sculptures with tentacle or fur-like outgrowths that are the result of porcelain being built up with thousands of brushstrokes.
A menagerie of more than 45 of the bulbous, rainbow-coloured objects ? some with golden trunks and antennae like deep-sea creatures ? were made especially for the Frieze Art Fair in London.

At up to a metre tall, the pieces include some of the largest created so far as part of the studio's ongoing Accretion series, which is named after the production technique used to create it.
It was especially developed by the twins, Nikolai and Simon Haas, to mimics the natural, almost sedimentary growth patterns of stony corals or tree fungi, which are built up gradually, layer by layer.
"Any physical process repeated identically in the long-term will yield a form," Simon Haas told Dezeen. "Take the dip that forms in worn-down stone stairs, or the various cave formations whose shapes are determined by what surfaces water drips onto or off of."
"So I wanted to see what would happen if I brushed wet clay onto drier clay over and over and over, and that's how accretion was born," he continued.

This process is applied to a clay sculpture, which is first scored to create a hold for the porcelain slip, and then left to dry half way through the process.
After that, several rounds of the porcelain are applied, with each layer adding about 0.1 millimetre in lengt...
