Walking through downtown Chicago, on Michigan Avenue, I recently saw this on a temporary construction wall:
I’m not normally a fan of graffiti or defacing public property, but if you’re going to do it, I guess this is the way to go.
When I walked by this wall a few days later, the markings were covered up in black paint. I understand not wanting to encourage criminals, but this perhaps this particular work of art/science deserved to stay up, educating the city’s residents and tourists as they pass through an ugly construction tunnel.
Regular criminals: Stop damaging our neighborhood.
Math/science geek criminals: Keep doing what you’re doing. You are making a difference.
