I don't know how long this has been kicking around the internet, but today is the first time I've seen it. I don't think it's the kind of poetry Sam is looking for so I'll just post it here.

> ! * ' ' #
^ " ` $ $ -
! * = @ $ _
% * ~ # 4
& [ ] . . /
| { , , SYSTEM HALTED

The poem can only be appreciated by reading it aloud, to wit:

Waka waka bang splat tick tick hash,
Caret quote back-tick dollar dollar dash,
Bang splat equal at dollar under-score,
Percent splat waka waka tilde number four,
Ampersand bracket bracket dot dot slash,
Vertical-bar curly-bracket comma comma CRASH.
