This is the sixth bimonthly 'What are you working On?' thread. Previous threads are here. So here's the question:

What are you working on? 

Here are some guidelines:

• Focus on projects that you have recently made progress on, not projects that you're thinking about doing but haven't started.
• Why this project and not others? Mention reasons why you're doing the project and/or why others should contribute to your project (if applicable).
• Talk about your goals for the project.
• Any kind of project is fair game: personal improvement, research project, art project, whatever.
• Link to your work if it's linkable.
