Storyboards can be a great option for your case presentation. Storyboards can be as effective (and sometimes more effective) than an animation. Additionally, storyboards inevitably cost less than animations, since doing a storyboard is generally the first step of an animation, and then a significant amount of time (and money) is spent actually animating and rendering the concepts. I also have found that storyboards are easier to get admitted into evidence, since judges see them as simply helping explain expert or witness testimony.
