Create an image that shows some kind of a mysterious glow. Remember, this challenge is basically about lighting.
edit: it seems a lot of people are misunderstanding the term 'mysterious'. From dictionary.com: "3. of obscure nature, meaning, origin, etc.; puzzling; inexplicable." Light sources from generally known and explainable circumstances do not constitute mysteriousness!
