Tutorial using CI 8.0.0

[inovateqsa]

Is there a way to make animated buttons in the custom installer, or CIU?

Here is the scenario:
I am making my own installer for DMC, remember how in the 3rd game you could 'Slash' or 'Shoot' the loading symbol and add scars to it?
I want to have a slash mark appear whenever someone moves the mouse over the button, when they remove the mouse it stays, then when they move the mouse over the button another slash mark is added (So the number of slashes increase every time they move the mouse over - up to a limit).

Any Idea's?

Aside from that scenario, is it possible to have genuine animated buttons (Like gifs) as well.
And animated backgrounds?

The DMC buttons are my top concern right now, but I would appreciate it if someone could answer my other questions too.
Any help would be appreciated.

Thanks.
