Cant you just do it yourself with the wiki page here?

its fairly easy if you follow the instructions.
you're right, I learned how to make WPS's in around an hour or two, some of the more tricky things like conditionals, and alternating sublines (and then sublines with margins) take a bit more time to get used to coding. But really I'd compare the WPS code as similar to HTML in terms of how easy it is to learn.
Some WPS are intended to work with just changing the backdrop, see 'kelp' by Dan Manners and "twilight" by Twilight In Zero both for the ipod video.
Markshelfer, if you still feel like just making a request, I'd take a shot at it:
what exactly are you looking for layout-wise?
