Ha! Just after midnight, so this counts for the 24th
A friend of mine issued a challenge. He asked me to write a haiku in "pilish", which is an unusual restriction, where the number of letters in each word follows the digits of Pi, so 3 letters in the first word, 1 in the 2nd, 4 in the 3rd etc... (to a few decimal places, this is the pattern: 3.1415926538979323...)
My friend got the idea from the short story Cadaeic Cadenza, which is all written in "pilish". Cadaeic Cadenze is an amazing piece of work, using crazy restrictions, and reads quite well. The story is long enough to reproduce 3835 digits of Pi. His section mimicking Poe's style of "the Raven" has to be read to be believed.
My humble haiku:
ink a line, a group.
seventeen to create verse.
the haiku appeared.
