I was hoping to have more done to show by now, but I did get another Quickstart Expressions tutorial knocked out about two weeks ago...it's here, in case anyone missed it.
At the moment I've got another ball bounce exercise I'm working on and an update to the animation I made for my friend incorporating Matt Campbell's suggestions.
I've also done some tinkering on one of my nagging rigging issues...I periodically go back to a couple of those to see if I can come up with a solution. I've put in a couple of feature requests because of this one, but I may have to add one more, I'm thinking. I just have to think up a request that makes sense within the existing system.
I've still got a rig addition to make and some modeling on the generic character that I'm trying to improve.
It seems unrelated to Bertram, but in reality it's all going to help with the animations I want to make with him...he's always my main focus even though it may not appear to be the case at times.
