The Core Framework team has just opened their marketing place for UI kits and templates. At launch there are two offerings for Oxygen.

Paul Charlton recently made a video showing how to use the Core Framework with Bricks. He has released a follow up companion video showing some more steps you can take to get the most of using the two together, such as adding custom classes and variables in the Core Framework UI instead of in the Bricks settings. The advantage of doing this is that you create your own set of styles that you can easily reuse on other sites rather than manually adding the settings to Bricks each time.

Here is a nice demo from Paul Charlton using the Core Framework with Bricks. It is a good overview of what is involved in setting it up and the benefits of using a framework.
