MAA Found Math 2014 - Week 36

In an open square in downtown Brisbane, Australia there are several sculptures like this in different sizes, found by Jonathan Kane.

The spheres are a form of street art by sculptor Donna Marcus. Watch a video of the "stream" collection being installed at http://donnamarcus.com.au/galleries/8_on_the_screen/steam.html. There are a number of wonderful math-inspired artworks on her site.
