Slide show controller

Hello everyone… I want to create something like the slideshow from the front page of “”. My problem is that I want to make something like the “little controller box” on the downward right side between the slide show and the videos, and I have no idea how… The “controller box” shows how much time left it has before switching to the next slide. I want to make something similar to it and also that can be able to pause time so it wont switch to the next… can anyone please give some advice?! thanks in advance
