Wrapup stuff

* Note: A lot of "How would you design this" stuff today
  * Lots of the design seems arbitrary
  * But some parts have some clever hidden stuff
    Lowercase and uppercase are 32 apart (easy to switch)
    Letters are in order and contiguous
    Below 32 is "special character"; (makes it easy to check for special characters)
* Today's really bad joke: Who has my ung?
