Using haikus as stanzas often leads to exceptionally tight writing, as here in Norman Schwenk's "Movie," on Poetry Daily today:

the twin towers shown
as an establishing shot
saddens many films

There's something to be said for capturing something in words that others might already have noticed but never quite fully registered.

I first read the poem on PD's new iPhone app, which is excellent.

Poetry-wise on the iPhone, I've also been enjoying Poem Flow and the Poetry Foundation's new app.
