Scrolling credits on a user form?

I am still learning user forms so please excuse any mistakes.

I would like to make scrolling credits appear on a user form. I did find one solution on the net but it didn't scroll smoothly.

I wondered if it would be somehow possible to link a scroll bar (set to Visible = False) to a user form object and then use application.ontime (upon initialize) to slowly scroll the words up the form?

Or is this just wishful thinking on my part?
