Tank Art

There is an art movement that is taking Australia by storm.  It started with wheat silos in the country areas, and now it has spread onto public buildings in the suburbs.  This is a water tank within walking distance of our house.

It appears to be an interpretation and extension of the street art which has been around for years.

To me it looks like the underside of fishes zooming around the tank.  However you choose to interpret it, it's pretty spectacular.
