I need metaphors for these words USA and computer.

A possible metaphor for the United States of America? Uncle Sam?

And for computer? Calculating machine?

That's a bit gentle; I call mine an infernal machine (that's not really a metaphor - unless you have an etymological turn of mind and understand it as 'coming from Hell').

I have a friend who calls his a confuser.
