New Curve Functionality?

This picture of some Curve function was Tweeted on Blender’s page several days ago:

I’m not certain what it means, whether it’s a preview of some work that’s being done on new Curve tools or what. I asked the original poster a question on Twitter, but he didn’t reply. Does anybody know what this means? (I was originally hoping that it was adding some new Curve animation tools, to provide Illustrator-like capability or something like that, but I know that that’s unlikely.)

Looks like a part of Psy-Fi’s GSOC 2013 project. You can follow all that on this thread:

Okay, that looks like it explains it. Thanks a lot!
