Maybe helpful to somebody or someone can improve on it. I wasn't really sure where I was going with this to begin with. Probably not the best content* for the concept.
Very, very interesting idea, @MaxZieb!
If you please, as you people taught me very well in this forum about the sliders issue, I have made some improvements:
The improvements are related to the ball and the mouse cursor moving stick together.
All keyframes must be placed on Linear;
Because of that @jonathan had said in some topic, 100 pixels equals 1 second. If your workspace is 620 px wide, this means that the action in the timeline should be 6 seconds and 6 frames long (mathematicians will say better);
When you do this, you will not need to set the speed at the trigger to be 80%.
