I responded earlier to a request from a different facebook-based prompt but here’s the NaPoWriMo.net prompt:

Today’s optional prompt is to write a lune. A lune is a sort of English-language variation on the haiku, meant to better render the tone of the Japanese haiku than the standard 5-7-5 format we all learned (and maybe loved) in elementary school. There are a couple of variants on the lune form, but just to keep things simple, let’s try the version developed by Jack Collum. His version of the lune involves a three-line stanza. The first line has three words. The second line has five, and the third line has three. You can write a poem that consists of just one stanza, or link many lune-stanzas together into a unified poem. Happy writing!

You know I love me haiku. This was harder than it seemed it should be but here you go. I will await further haiku to arrive later tonight:

this small ring
watery melt circling the pond
ice grey sky

no skies reveal
who traces the clouds so
swirling the horizon

this half sky
waves and undulations of clouds
an oceanic dream.
