This is an unusual work by Simon Gauntlett and Matthew Ngui and unveiled in 2015. It was created to record the 200,000 signatures of the State's school children that had been reproduced on tiles surrounding the bell tower for the millennium celebrations. These were later demolished to allow the development of Elizabeth Quay. Interesting concept with the signatures now etched in copped and affixed to the steel structure. Wish that we had known about the fibre optic light display after dusk. The sculpture incorporates 426km of optic fibres which illuminates the signatures. Another visit to see this display when next in Perth overnight.
