Oh that's a good question...Let's see...
It was really about the juxtaposition of the flower and the starfish, and the way that implied some kind of strange, new life through the simple act of laying one image over another. This resonated with my ideas about textual juxtapositions giving rise to new imaginings (I talk about this a bit in my Yes Indie'd interview.)
I also made that image within days of coming out and starting to transition (more than 2 years ago now), and this notion of blossoming into as-yet-unknown life, felt very personally important to me. As I talk about in the Preface to the hardcover, the game is really intertwined with, and emerged from, my first experiences of transition and queerness. That image capture those experiences for me.
