I
wrote
a poem
on a page
but then each line grew
to the word sum of the previous two
until I started to worry about all these words coming with such frequency
because, as you can see, it can be easy to run out of space when a poem gets all Fibonacci sequency

It is indeed by Brian Bilston - page 111 of "You Took the Last Bus Home."
