Wow. That's a lot of toys. Now I'm totally jealous!
Some people have a weakness for Hello Kitty. I have a weakness for robots, or mecha if you're talking the language of anime. Even though I don't write stories with robots in them, they are a constant source of inspiration. Some of my best memories from childhood are of watching shows like Transformers and Robotech or reading about great RPG universes like Battletech.
Plus playing with a transformer when you're stuck on a story point is great for jogging things lose.
