Rictameter - Form

This is without a doubt my favourite modern form.  It looks pretty on the page, with its diamond shape; the even syllables give it a nice regular sound when read aloud; the bookends make it clever and give you an opportunity to shift meaning or wrap it up completely.  Really, it's a gem and the best thing to have arisen from Dead Poets Society (which is on my top ten hated and overrated films of all time).
