This is a video demonstration of The Apprehension Engine, a conglomerate of musical instruments built by Tony Duggan-Smith so filmmakers can create their own creepy sounds instead of paying for stock audio. Admittedly, it does sound pretty scary. Now I’m not saying I peed my pants– “But you did.” Right, but I’m not saying it because that would be embarrassing. “But you just admitted to it.” That’s it, I want to speak to my lawyer.

Keep going for the eerie demonstration.
