Metaphor for creativity

What is a good metaphor for a person that is creative, or for creativity in general? I find nothing when searching and nothing really comes to my mind? Help appreciated!

Analogy

Analogy is the broader term for metaphors and similes. Pick an aspect of 'creativeness' that you want to emphasize and find a suitable analogy. If it's originality, or ingenuity, or free-association, or the ability to constantly produce, any of these might be analogous to some other well-known thing (a garden, a factory, a waterfall, a flock of sparrows) and by making the analogy you emphasize that aspect even though these things aren't normally associated.

Metonym

Metonym is an associative concept, like "Wall Street" (an actual street in New York's financial district) standing for the stock market and the industry that surrounds it. Similarly, "Hollywood" stands for the movie industry and movies in general, as well as being an actual place where film studios were located.

Synecdoche

synecdoche is when a part represents the whole (or vice-versa) so an artist has "an eye", a musician has "an ear", a dancer has "legs". These are specific things they use in their craft but they stand for broader concepts than what the word actually means. A hitman might be "a hired gun", and an attractive woman might be "a skirt".

Literary philosopher Kenneth Burke grouped 1 more language "trope" with these: Irony. It would probably be used to represent the idea in a negative way, but possibly revealing some underlying 'truth'. The irony of creativity might be some of the negative aspects of art and artists such as an unreliable work ethic, crippling self-doubt, disregarding of morals or society's norms, or inconsistent results.
