4th task of the 7 GUIs.
Made with Vue and Xstate -- a framework for using finite state machines (FSM).
7GUIs.--.retro.--.4.webm

They don't use Vue but were helpful for figuring out the logic and syntax -- things like actor invocation and eventless (always) transitions (and when and where to use them).
