I've created a mask that fits one informational card. I then created interactions for every card that moved it from its original position to the mask area.
If there was an 'active' state in the slider that pertained to the active element I envision setting scaling to 1.2 on the active card.
making this easier:

It would also be nice to have an 'on click' action for slider slides that would move them to the 'active' position.
