It's a form of artistic expression for some people (like me) who aren't as great with paper and pen but still have ideas and patterns and concepts and abstractions to express.

Watching the data just flow through the pipelines and pathways you've laid down for it, creating spectacles from what is essentially electricity running through a rock. Being able to create an interface between a human mind and an inanimate dead block of dug out and processed ore, feels like tapping into the metaphysical.

(Yeah I'm pretentious with words)
