This is a very vaguely formed idea, and, I'll admit, inspired at least in part by new media stuff - but not really, because it came to me last Thanksgiving and I haven't gotten around to doing anything with it. But it fits well thematically!
Basically, I want to start with time-travel or alternate-universe travel - I think deliberately vague, at first, as to which it is - and a student thrown back into a Renaissance-type era, very unprepared. She doesn't have much with her; the hole she stumbles across on her way to class, or something. One thing she does have is a copy of Shakespearian sonnets, and possibly other poems as well. In order to make some money, the protagonist has the genius idea to sell the sonnets to a printer and circulate them anonymously. After all, they're immortal classics, yes? So they should, in theory, be popular in any time or place.
She does the first lot as a batch, and then starts hoarding them out, in order to make them last longer. She also destroys the original text, and copies them all out in her own hand, in order to keep her secret better. The poems circulated by the anonymous author become all the rage - in part because of the mystery surrounding them - and make her enough money to keep herself comfortably in the world she's found herself in, and of course after a while she gets bold enough to start altering the sonnets she puts out, and then to writing her own, using the fame of the early sonnets as a sort of springboard. I haven't quite decided how it should end. I'm sort of leaning towards the revelation that the world she's in is ours, that she's been time-travelling, and it ends with Shakespeare gathering up the sonnets he likes - editing them in places, of course - and printing them up to claim as his own work which gets passed down to today, as a sort of cycle of plagiarism. But I do feel a bit bad doing that to poor Shakespeare.
There were a couple of media I was thinking for this story:
1. Mash-up. This one seems the most obvious. I might do it as a set of sonnets - some Shakespearian, some not - each as the header to a section of the story. Maybe I would intersperse lines from the plays, or films such as Shakespeare in Love, as well. A story about plagiarism told through plagiarism! Very metatextual. It could all be bound up in a neat little battered book, as if it had survived a couple hundred years to Bring The Truth To Us. Or, if I wanted to go a step further,
2. Hypertext mash-up. This one I'm kind of leaning towards - telling the story with links to the poems and relevant real-world documents, inserted more heavily towards the end when it turns out that the world in which the protagonist finds herself is ours after all. This has the advantage of allowing me to photoshop some of the poems onto period-esque looking pages, while allowing an infinite amount of space and a visual contrast between the actual events, the poems, and the edited poems.
3. Mixed movie mash-up. Yes, okay, I like Shakespeare in Love. But clips from Elizabethan-era films linked with voice-overs might be a cool way to tell this story, although probably beyond my technical expertise.
