Looking to adopt/build a small Active Record Mapper

Hello, I've recently converted to PHP from ASP, and I'm so
glad to see
such great OOP support in PHP5!  It's really a great thing.

I've adopted ADOdb as database layer, and I'm wanting to use
the Active
Record
and Mapper patterns, along side with it, if anyone could
recommend an
open-source
project that could help me do that, or give me a few
interesting
articles, I'd be glad.
