Shapes In The Scum

It's like spotting shapes in clouds, only a bit more unpleasant.

It seems that somehow a large container of some kind of oil got spilled all over the pavement and road. The first time I went past it I thought "Oooh, blip material." The second time I went past it I slipped a bit and the third time I crossed the road to try and avoid breaking my neck! Thankfully somebody has now been by and put down loads of absorbent stuff that looks like a mixture of flour and cat litter to soak it up.
