Day 17: Ruler art in Grafton

Before we left Grafton today we visited the Grafton Regional Art Gallery. We have been finding regional galleries to be very interesting indeed. This one did not disappoint.
 
The photo shows one of a series of artworks made of rulers. I feel badly that I didn’t record the artist’s name. We are now about 260kms away so I can’t pop in again. I have tried unsuccessfully to identify the artist via Dr Google.
