XD I am familiar with the experience, as I do it, too, even with books.

I've been so immersed in Trek (and Stephanie Brown >_>) lately that half the prompts I can think of over on the Invaders art tree are Trek crossovers. Peggy Carter meets Kira Nerys; "Not the Maquis I'm used to". Horton vs Soong: fight of the androidmachers*! Namor Disdains The Vulcans ("Desert planet? Blech!"). Steve doing illustrations for a new story by an elderly Benny Russell.

* Don't get me started on the prevalence of fictional creators of androids being Jewish and how it ties into golems.
