The scrolling lines start all together, but since the lines have different lengths, they get out of sync quickly. Since the motion is slow, you can read parts of different lines at will, moving over the range of the poem in a new and surprising mode. Try to read snatches of lines as your eye moves up and down while the words move right to left. Stay with the poem a while, reading and remembering phrases and how they fit together.
I give the poem below in normal text view, you can read it that way but the whole effect of synchronous moving verse is lost. Without the motion as the way a HyperPoem asks to be read, this becomes just 'another poem'.
Floating all summer lazily on the fresh grown alder tree
the leaves flee in fright before the roar of a hostile wind
The wind laughs aloud at their hollow fright, now swirls again
hoping to tear a stem loose or break a branch
hurling it to the far end of the garden plot.
The wise willow by the fence at the far edge of the yard smiles contentedly.
knowing its dangling branches yielding before the wind will not break
But now Aeolus has at last spent his mighty force
overwatching SUN raises its radiant eyebrow,
and goes to rest a while with his brother winds.
Now can the alder can take time to groom and rearrange its green display
gently wetted by a rising mist that cloaks the forest trees.
The smell of rain is in the clouds and rain will be coming soon
washing away the dust the wind blew in, and ever so gently now
baptizing the forest with a blessing of peace and quietude.
