I suppose it is an art installation. It wasn't there much more than a week I think. A sign informed me the land belongs to Vic Track. Vic Track is part of the public transport bureaucracy responsible for train and tram tracks. I can't judge its artistic merit, but as I always say, if it attracts attention and make people stop, look and wonder, then it works. It was set up on some unused vacant land near Moreland railway station.
