Also the title of a poem which I first saw as an easter egg on Sadly I have no idea who the original poet was.

i knelt down next to you
watched you laying there
i put my hand on your forehead
saw your eyes open
it's time to wake up
there are a lot of people who want to meet you

you looked back at me
stared into my eyes
i'll never forget what you said
"you are the builder"
"the creator of things unseen"
