Lauren Joan Lysaght's latest exhibition was inspired by the pseudo science of phrenology.
Olde Lumpy is showing at the Rayner Brothers Gallery until October 2. It features model heads adorned by strange lumps, which are made of anything from walnut shells to crystals.
The idea for the exhibition when Ms Lysaght came across a quote by author L. N. Fowler explaining the value of phrenology - a pseudo science popular in the 19th century, which was based on the concept that a person's personality could be determined by the shape of their skull.
"I thought it was rubbish," Ms Lysaght said.
"But people didn't question it back then, just as people these days don't question things they should."
