I added a video recording too. Essentially, the application is backed by an ObservableSet<String>, and every time it changes it pushes itself through an RxJava Observable (not to be confused with the JavaFX ObservableValue) where it can be transformed in a myriad of ways using RxJava operators. Three subscribers represent the ObservableSet<String> in three different ways: a simple ListView, a ListView of distinct lengths, and a concatenation in a Label.
