Shelley Javier has shared the highs and lows of a new venture.
The Rooty Hill resident is among eight university students and graduates who have created the light installation Venture for the Vivid Sydney festival.
The five, three-metre sculptures made with polypropylene tubes and LED lights diffused with foam will react to movement once installed on Cambridge Street in The Rocks.
Shelley said there had been more to the project than anticipated: "Half of its programming and half its hardware — building the bases, ordering and finding manufacturers who supply the things we need," she said.
Siblings Alexander and Lauren Murphy were also part of the group which designed the sculptures.
"Lights will flicker across the lane in different colours and patterns and as someone comes closer it'll do something different," Lauren said.
"Because we're all uni students or just about to leave we decided the installation should mean something, and that became the concern of entering the workforce and not knowing where we're going to fit; people are always saying how graduates have a hard time finding jobs at the end of uni — that uncertainty is communicated by the diagonal flickering lines."
Alexander discovered an interest in lighting through school musicals.
His HSC visual arts project was light-based: "We went back to design basics and came up with this," he said.
"To be part of the sculpture side of things with the lighting was a big interest for me."
