Plank / Variation on a theme

Came across this picture from a current exhibition in London. It shows a plank happily leaning against the wall (you guessed it, it's the very same plank and the very same wall you see above).

Thought this installation could use a little more complexity and added the piles of sawdust, the chainsaw (always comes in handy when you've got to work with planks) and the letters W.T.F., which of course stand for you know what.
