Martin [Rusev]'s project is called Crystal. It's an object-oriented wrapper for the venerable mysql and pg extensions, with the goals of making SQL more human-readable, and providing a library that is lightweight and easy to learn.
There's code examples on the site of how to use the library. Bill also mentions some of the things the project does well and a few things it doesn't - like leaving out some of the advanced SQL functionality in favor of simplicity. He also mentions concerns about SQL injection handling, code not shared between database handlers and the unfinished nature of some features.
