Picture a rat crawling through a sewer pipe. The pipe is dark and endless. It stretches out in front of him, endless darkness, and behind him, a long, endless tunnel of darkness. The rat has been crawling for so long that he no longer knows which way he is going; time seems to have stopped and he is no longer certain that he is moving forward at all. His foot slips against the slimy side of the pipe and for one moment he falls asleep, and while he sleeps he dreams that he is a software developer working on this very project. Standing here. Talking to all of you. He wakes up a moment later, realises he is back in the sewer pipe and his body glows with a tremendous feeling of relief. It’s a beautiful moment.
