Six years after the crisis and now being known as 'the' place to be, Buenos Aires is trying to catch up to what it thinks a world-class city should look like. This includes fixing all of the public areas at the same time (and closing them all in the process) and a lot of renovations, in addition to plenty of new building being built. These cranes have been around for some time (sitting unused for almost as long), but they're getting a new coat of paint. You can see what a difference it makes - the left one is not in shadow, it's just that old and dirty. I kind of like the older ones, the new yellow looks so unreal.
