I do love the idea of Solar Equation an installation art work at Federation Square, Melbourne.
Besides being beautiful (and even a little fearful with this massive sun bearing down) the installation is intriguing because if you are there in Federation Square and have an iPhone (persuably also iTouch) or iPad you can interact with it through an app called Solar Equation. The installation only last until the 4th July so if you have one of the aforementioned tools and find yourself in Melbourne, go play with the sun, for me?
