I’ve recently started pushing updates to a new project on my GitHub profile, tentatively named Feather. The idea was to build a tiny MVC framework in PHP, partly to see if I could. I’m slowly adding to it over time and its in a highly unstable and incomplete form, but feel free to take a look.
You can find the repository here: https://github.com/BobLoco/Edit-in-Place-jQuery
It’s not exactly a complex script and probably needs some tidying, but I hope it’s of some use. Full credit should go to Drew McLellan at 24 Ways, who provided the original example in Prototype.js
