Soup of darkness

Meanwhile in Germany, the EU's ban on incandescent bulbs has sparked a backlash, including hoarding and runs on stores. Expect much the same here. It reminds me of the opening lyrics from Imogen Heap's song "Tidal":

Before electric light,
You paddled through the soup of darkness as a crocodile,
Cherry picking in the river,
I would leave crisp note footprints at the Bankside

Watch it closely you will see it begin to move
Watch it closely you see it begin to flicker

OK, maybe that's not what that song's about, but it's at least open to interpretation.
