Renga is a 15th century Japanese collaborative poetry form. The kick-off poet writes a hokku (three lines, 5-7-5 syllables each, what we now call a haiku), the next poet adds two 7 syllable lines. The third poet takes the 2 lines and adds a 5/7/5 set of verses. And so on...see this example taken from Miner's book Japanese Linked Poetry.
Renga can be serious or funny (haikai no renga), but the game is not so much as to follow a single through line in the imagery, but to link and shift. I enjoy the ways in which the shifts can make me blink, and tsukeai, unusual and evocative juxtapositions of words.
without my glassesIf I'd been in the game, I might have responded with
i’m groping trying to find
where my glasses are
where my glasses areAnyone is welcome to play!
smudged by thoughts I cannot catch
I see drops of grace
