Hubbub, an environmental charity in the UK, wants to encourage people to dispose of their garbage in a proper manner. So it created a series of urban trash cans that make disposing of litter fun. In this case, people can vote with their cigarette butts for whom they think is the greatest soccer player in the world: Lionel Messi or Cristiano Ronaldo. The managers can also swap out the question for others that encourages debate and thus proper garbage disposal.
You can see the other trash receptacles at Booooooom, which address the annoyance of chewing gum left on sidewalks.
