From Oz

[RiverNotch]

The lone and level sands that fill the bowl
of human understanding do not shift. The world we live in does not move -- is, ultimately, finite.
Our pride has no horizons, and our goal
is lasting glory; to this world we gift We seek to make our mark on this world, so that this limited world becomes in our eyes infinite.
such splendid dreams – but who is to recall And thus we make art,
where once we trod, for footsteps always fade art which should eventually die
and parchment rots to dust while pillars fall. on this our limited world's end,
Mortality becomes a beggar’s trade, such that we dying folk are all made poor --
yet were our lives not hemmed by earthly thread 
would inspiration take that vital turn? -- yet would our works be bettered with immortality?
Or would our patience stagnate us instead? Or -- well, you put it frankly enough here.
‘Tis death that makes the fires of greatness burn. 
Take ev’ry breath with eyes cast to the sky –
there’s time enough for grounding when you die. Thus, from death springs art -- and there's no real reason to be all meh.
Eh, somehow this doesn't read as subtle as your other stuff -- I'm sure taking death as the wellspring of art is as tired a theme as Homer. It works, but for me, it's no favorite -- and as an earlier crit noted, it does feel like a wasted opportunity, especially with that double-edged title, and you referencing one of my all time favorite poems. Although perhaps that is the point --- I suppose this is meant not only to launch from Shelley, but to reverse it, with not only the plot but the gut-feeling turned upside down. Of course, if that's the case, I think the title being double-edged works against the piece, or maybe I'm just missing all the Wizard references. Technical notes:

I do find "gift" to ring a little archaic, but I'm not sure you'd want to sully your perfect rhymes with the better-in-my-mind give. I do like bowl/goal, though -- that image of a bowl of sand (and a literal bowl, not the sort that plagues starving lands) really sets the idea of a finite world.
Fossilized footprints do exist, though. A silly, but not necessarily unimportant, thought. 
"While" is definitely too weak -- as? and? you could somewhat echo Shelley's diction there, go "always fade, / and parchment rots to dust, and pillars fall." but that's sort of weak sauce too. In fact, I was sort of banking for something a little more evocative, than good old parchment rotting, pillars falling -- either a stiff stick to Ozymandias and focus on them pillars, or a shot of modernity and talk about, say, websites dying, hard drives getting cracked.
"Mortality becomes a beggar's trade" sounds like a reference to something, but even to what sort of something, I can't say. If it's entirely original (the method of saying -- I'm sure the idea isn't), then props for proverbiality. 
I'm a little irked about "take that vital turn" -- as if what we make now isn't vital enough. I mean, if the point of that line was to ask whether we could do better as immortals, I think it sorta fails, in so much as it implies more that what we already do isn't already beautiful, an inconsistency with "such splendid dreams". It could be a bit of a joke, "vital" meaning life --- but still, the readily apparent meaning fails, so it fails, for me. The next line works wonders for me, though -- the image it strikes is quite the chord.
And then "tis'" and "ev'ry" ruins it, for me. I mean, one of the things I absolutely love about Ozymandias is that it doesn't sound old -- no such silly contractions. And even if this is meant to be a reversal of that poem, I don't think it should be to the detriment of readability. Making "death" an active actor would definitely work, I think, but I'm sure you've a far better how in your mind. As for every, who yet says eh-ve-ry? (or if they do, I'm sure they'd alter to the common, finding the rhythm broke).
Yeah, a stronger verb than "take" would work better -- and somehow, "eyes cast to the sky" doesn't sound right. And I'm not sure the whole electricity thing with "grounding" is intended, or even works, I didn't get any shocking vibes from the rest.

Still, all is lovely.
