Street art. Why not?

A couple of days ago I started a collection. A collection that made me smile. There are too many boring but functional sights in cities so why not brighten them up? In so many cities this would be seen as vandalism but in Brisbane it's been embraced. From what I can gather, these are traffic signal boxes and I've loved collecting them. 

Edit: 9/11/14 found some more!

22/11/14 and another one!
