Your code contains a displayDaftPunk() function.
I would expect to see the scrollDaftPunk() and scrollDaftPunkWithPause() functions in the same file.

Looking at your code, you could certainly make it tidier and more general.
Then you would be able to display general messages in the different styles by simply passing a string.
