Last week the Australian city of Melbourne installed concrete blocks around the CBD. The "anti-terror bollards" were put in place to stop vehicle attacks on pedestrians.
In response to the not-so-aesthetically pleasing bollards, Melbourne artist David Gray decided to turn the cubes into an art space.
"I did not want to make any fun of that, or take away the memory of people who were affected in January this year," Gray told ABC Radio Melbourne.
"The City of Melbourne could turn this into a fantastic art space, there [are] five panels [on each bollard] which artists could just cover with amazing temporary stuff."
