Gerald Weinberg's Secrets of Writing and Consulting

I am a music box.

Though I embody the finest science and craft, made entirely by hand, I exist only to create beauty and pleasure.

I can be played closed, as a mystery.

I can be played open, when every part is open for inspection.

Yet though every part can be seen, I cannot be understood as a mechanical object.
I need the touch of human fingers to wind me with energy, adjust my gears, and start my music.

Without human contact, I am merely a lifeless decoration.
