Sometimes, just sometimes, a week of work has been so eye-gougingly frustrating, that the only way to cheer yourself up at the end of it is to create a wallpaper based on the knitwear of your favourite Danish detective.
Feel free to use it yourself: just press and hold to save the selected image above. Navigate to [Settings] and [Wallpaper]. Select to [Choose From Camera Roll] and select the Grid-App you wish to use, when prompted DO NOT scale and hit [Set]. Bosh. Done.
