I've blogged about this already a few years ago but can't help myself. It's such fun.
Nick Montfort decided to write by constraint, limiting himself to the use of the top row of his keyboard: q w e r t y u i o p, and no other letters. He wrote a poem and called it "Top Row Retort." It was published in 2000 in Word Ways: The Journal of Recreational Linguistics.

Top Row Retort
I tore out type ere I wrote, to type up top:
upper typewriter row, pert repertoire.
Reporter, I quote to you: To write, pop type out.
Retire typewriter row two. Your tri-row?
Rip it out, too. Tour your top row territory.
Queer tip, you retort? I worry your poor typewriter?
To torque it out -- typewriter terror?
You require row two, your tri-row prop?
You pout, try to quip. (Poor etiquette.) You titter.
(Poorer propriety.) You utter uppity output?
Quiet, you! Quit it! You purport to write.
I tire to peer to your rot, your petty writ,
to eye your wire report. You write pyrite,
terrier to torpor. I pity you, preppie yuppie.
I tutor you, tyro, to uproot your trite tree,
put type to pyre. Rupture type. Write to write.
I erupt. I riot. I prototype pure power
to write. I, upper typewriter requiter.
I outwit you, too. To perpetuity, I write poetry.
You, to put it true, putter out rote poop.
