[Baypiggies] A mini-decorator workshop

It's the same exact set of slides everyone has seen. What I want to do different is have us in a teaching environment working at our own pace.
So, we can't do it for a talk since we already have -- it'd be a complete repeat. What I want to do is a different format than baypiggies general meeting.
