Another in the series.  A sketchgroup member suggested that I blog about this series (from earlier when they were heavily geometric.)  I am working on a draft that puts down some thoughts on the whole thing.  It's not a very technical write up, but will explain more the idea and drive behind the whole thing.  Lately my style has been shifting and recombining since a month ago- so I think it would be good to follow the suggestion to put some thoughts down about what I have been doing from earlier in the series.
