Oulipo Galore

I really should be doing other things right at this moment, but as I've stumbled on a fascinating website - in fact Oulipo's own - I just had to linger. I've no time right now to speak of its many delights, although I will say that they include a huge list of constraints, such as the grafted alexandrine, the simple immoral (the opposite of the simple moral), and the snowball, which is a poem starting with a one-letter line, continuing with a line with a two-letter word, and so on until a certain number of letters is reached. A melting snowball does the opposite, and starts with the longest word.

There's an additional constraint for many people, though: it's in French. Oulipian madness here.
