I made a rather simple splash art and a Reflux profile install call for my UI that I've yet to release:

(I'm on mobile so pasting code is a bit tedious)
I just have a simple frame animation play and at the end of it call a function that can display a simple StaticPopup which can then call the Reflux profile swap.
