Leaf by Niggle
This story recounts the strange adventures of the painter Niggle who set out to paint the perfect tree. But he sensed that he would be snatched away from his work long before it was finished, if indeed it could ever be finished in this world. For it was in another and brighter place that Niggle found his tree finished, and learned that it was indeed a real tree, a true part of creation.
