Oh the usual "a bit of everything". Anime (super excited for the chainsaw man movie!), cosplay, physical layer networking, 3D printing, the Borderlands games, a bit of warhammer (for the lore, Trayzen x Orikan 4 lyfe), elaborate kinky bondage, etc.
I was only kidding a little about the mad scientist kink, weird tech in a kink context is my absolute favorite.
Howabout you?
