There were endless discussions about the crane, spend tax money for a piece of rusty metal and call it art? Or rather spend it differently? Or not at all? There was a vote, more endless discussions and finally, the crane was installed.
You like it or not, there is no way you can argue over art and taste. If you happen to be in Zurich, go judge for yourself;-)
We all know that Art is not truth. Art is a lie that makes us realize truth, at least the truth that is given us to understand. The artist must know the manner whereby to convince others of the truthfulness of his lies. ~Pablo Picasso
