It may not be exactly what you had in mind, but poetry and metaphor. I was a CS major with a Creative Writing minor. I picked the minor as an escape from CS but over the course of my career as a developer it has been some of my most useful time spent. When I was trying to write about a thing in terms of another thing (or reading other people's much better attempts) I would look at the lower level similarities and mess around trying to make the metaphor as tight as possible. Along with that, both writing code and creatively are mostly about constant revision. So both interests kind of played off each other reinforcing that process.
