Seddon artist Tim Craker enjoys converting disposable objects into artworks that can sell for up to $5000.

His curious creations are made from materials varying from plastic safety fencing to plastic forks and wooden chopsticks.

"Plastic is a scary thing," he says.

"It's a cheap and essential part of our lives, but we have to consider what happens when we dispose of it.

"Whirlpools of plastic exist in the great oceans."

Despite completing an honours degree in fine arts in the early 1990s, Craker continued to work as a veterinarian.

He left his long-time job 18 months ago to pursue his artistic passion full-time.

He says there is no formula for his creations.

"It's not an external program I'm following; it's more innate and organic.

"Driving around, I see things and think about possible transformations.

"Sometimes it's when I'm daydreaming on a tram or drifting off to sleep."

Music plays a part in his creative process. Working from a garage in Yarraville, he listens to tunes ranging from the B52s to the soundtrack of the television show Six Feet Under.

"You discover what turns you on visually - it's all about self-expression, self-development and self-exploration."

Craker's recent work has been inspired by plastic takeaway food containers, which he transformed into large three-dimensional objects in a project entitled Take(n)Away.

"The title refers to the fact that they are taken away from their usual role and alludes to the possibility that the viewer might be momentarily taken away."

Craker's work is on display at Highpoint's centre court during the Ways to Save Expo, which began on Monday and ends on Sunday.
