Art in the hallway near the bicycle parking lot

Those who want to get from the bicycle parking lot to the rest of the Röling Building must pass through two large white doors and a hallway. In that hallways hangs a work of art by Bart Beijer, Policy Officer Educational Affairs at OSA. The work consists of six plates depicting bicycles in unusual positions. The small sign next to the artwork gives a short version of the following explanation:

How people treat bicycles is a mirror of their soul!
Actually, it's a kind of a metaphor. How people treat their environment says something about them.
What possesses someone to hang a bicycle (someone else's) in a pole with purple tape?
Or to turn a bicycle (someone else's) upside down? And are you allowed to treat public space this way?
And if not, who does something about it? What does this say about the current zeitgeist?
Just a few questions that may come to mind before starting a new working day.
