Answer:
You find me behind the stars; or in a sixth seventh or third. It takes something round a computer and me to make pie. I am bigger than anything you can think of.
I rise and fall no matter what, only at finals rest do I not budge. What am I?
Deposit red liquid in me.
Every dawn begins with me. At dusk I'll be the first you see and daybreak couldn't come without. What midday centers all about. Daises grow from me I'm told. And when I come I end all code but in the sun I won't be found. Yet still each day I'll be around.
Glittering points that downward thrust. Sparkling spears that never rust. What am I?
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
