The Bonsai Story Generator takes any text fed to it (up to 6K) and randomly rearranges the text to produce new sentences. As you might expect this creates a small mountain of nonsense, but it also produces some interesting word pairings and clusters, a few of which can work as titles, prompts, scene ideas and more.
I took about 4K of my NaNo novel and Bonsai'd it, and then weeded through the results, deleting out the gibberish and whatever else was useless. Here's what I kept, along with some of my thoughts in italics:
Driving through the lionsgate to be ruined
But he should hurt a little as my son-in-law. (Beautiful line for a mean mama-in-law.)
She caught her ladyship's feathered bonnet.
She would have had a traveled veteran.
Tell the wound.
The man looked down into our society, Lady Hardiwick said.
Greville would send Prudence into tarts (I love this as a description of a compulsive eater)
Well, he beheld the mare.
Agitation kindled a gentleman.
The fact that she would do no longer.
She heard a kindly older brother.
As a girl she'd been silly enough to cross their path. (This sparked a new scene for me)
No man had fainted from her.
I haven't a groan.
You are a morning salon, abundantly furnished. (What a nervous man might say while trying to compliment a beautiful, well-endowed woman, maybe)
He is not indulging in the company as yet
the great house at Netherfield Park stood like a spinster (You can't imagine how helpful this was to me. Honestly. Hugely.)
Stand back, she can make himself sick again. (Instant, hilarious imagery)
Julian with no other sound.
He will look at the most generous good enough to be ruined (is there any better description for a penniless rake?)
Lady Maycott released a ridiculous fiction (A lot of us are prone to doing that.)
Miss Maycott, please allow any callers.
I don't care how often he will have us.
It will likely turn the decanter.
It is not the makings of our invitations
Built in pieces, Miss Maycott.
your kindness has no other sound. (I just loved this.)
You have a bloody clue. (as opposed to the cliched haven't)
I feel so dreadful for her, much of her too.
She sat back on her own feelings
The roads are recovered
I will cut open your hopes (this one gave me shivers, and is definitely going in the story as part of a rant.)
You can also feed poems, song lyrics or any other type of text to the generator to be bonsai'd; I do this sometimes with long, imagery-rich poems to get title ideas.
