Pallet City gets Photoshopped and colour inverted

I chopped up a damaged pallet for my brother-in-law's stove. The short planks were uneven lengths. When they stood upright in an old vegetable box it reminded me of a skyscraper city. Then I went a bit mad with Photoshop Elements. It's the sort of thing I do when I am too tired to do sensible things with my photos.
