What about HMVC? humm nettuts has one I think...
Maybe your series could be instructing using the most popular / proeficient / admirable / whatever librarys (helpers...) that community already created.
It could start a wave of fresh people devoting time to popular/interisting but old CI-powered tools, in need for maintanability/refactoring/attention.
example: Video series from one of the 3-4 excellent template libs available, or form-generators, unleashing the complete power of those libs.
Maybe round-up formats for some of the good libs/helpers aimed at same goal.
Or a CI-Skeleton generator series, that users could start their own skeleton-templates and generate MVC's or Modules from their own foot-print and DB structure..
My 2 cents...
