The mural depicted several drivers inside black fish, and one driver inside a pink fish.

A closer view of one of the drivers inside a black fish suggested that this was painted using a stencil.

A closer view of the driver inside the pink fish. This must have been a self driving fish, because the driver did not have hands on the steering wheel. He was also sipping either a cup of coffee or a cup of tea.

Three black fish arched across the side of the building. Notice that the steering wheel could also be the eye of the fish.
