Thirteen Ways of Looking

I found this selection from a poem online called "Thirteen Ways of Looking at Wallace Stevens."  The title, and, as far as I can tell, the poem, is based on a Wallace Stevens's "Thirteen Ways of Looking at a Blackbird."  It's sort of a delightful idea, though I'm not certain it worked out in the first poem.  (Unfortunately, poetry is not like pitching screenplays: execution matters.)  It may be, since I'm reading a selection, that it works better in the whole piece, which I don't have access to.
