Hi there!
I'm working on a project called 'Orbis', that is exactly the thing you are talking about. It's still in heavy pre-alpha, but it's most vital functions are working:
- A configurable interface, all based on a "stylesheet" class
- A class autoloader, that takes care of loading all classes and functions on "boot time"
- Loads of neat classes, all based upon each other and nice stuff like that 😉
It's object oriented all the way. I'm still trying to decide how the Stylesheet class should work (one global class for the entrie site or a new one for each object that uses styles) and wether to limit the system be only providing MySQL Support (DbConnection class handles that as is)...
Is that something like what you're looking for?
