The knitting of poetry

The Poetry Society in London is celebrating its centenary with what is being called the world's first giant knitted poem. The knitters don't know what poem they're contributing 12 inch square letters to, so the resulting FO will be a surprise to almost everyone involved when it is revealed in October.

It appears that they're still accepting participants, although I have no idea if international knitters can take part. Sounds like an interesting idea that should make quite a dramatic impact if it's fortysome feet long.
