Ah the World Wide Web! Such things you have to offer. No other place can you do so much and move so little. All kidding aside, there is a plethora of resources out there today via the internet. A while back I put a link in the Resourses and Tutorials box on my blog called the FIGURE & GESTURE DRAWING TOOL. I didn't get much chance to use it but it seemed great. Anyhow, I just used it. I set it for 2 minute poses, opened up a photoshop document (11"x17"), chose a big sized brush size (75: with the jitter up for texture, the minimum diameter down for a wide range of line & 30% opacity) and hit start. I just added a layer each time the pose changed and saved the document. To export all the layers in one fell swoop I went to FILE / SCRIPTS / EXPORT LAYERS TO FILES. It's a great tool for some quick pencil mileage. There's also an option to draw animals! Yes, I know, technically people ARE animals, don't be such a smart ass.
A big shout out and thanks to the creator of the site, known as Pixelovely.
