At Federation Square in Melbourne Nearamnew is a public artwork that incorporates the cobblestone paving. According to the Federation Square website, it is a vast paving design with poetic text inscriptions where fragmented voices of historical and fictional characters can be deciphered in nine locations around the site.
In 2005 I found that a contemporary character had added an inscription to another location on the cobbles. I don’t know how long it had been there. Australia joined the war in Iraq in 2003.
