An artist collective called Clock set up an interactive sculpture on one of the central squares of Budapest. The piece is an actual punching bag. Are they trying to raise the popularity of boxing? No. The explanation goes like this:

The main goal of the outdoor punching bag is drawing attention to the procreation of sculpture-theft/vandalism. It stands (and serves the city) as an appropriate target of human destruction...
Wanna' hit?

The public appreciated the concept a lot. The bag was cut to pieces in a matter of days.

It's a dome with a diameter of three meters with a boxing bag in the middle. People are supposed to "kill" that boxing bag instead "killing" statues overall the city. The idea worked great, the first bag was dead in three days. - Artificis reports.
