This post (and the linked project from it) covers how I use ARKit to make it look like the real world is being distorted by music: https://blog.mattbierner.com/reality-shaders/

I personally could never get very exited about AR apps that simply insert digital objects in the real world. Using AR to modify the world though opens up a lot of possibilities and I've been throughly impressed with how well ARKit can pull this effect off too. It even works great on the five year old iPhone 6s.

Give the app a try and let me know if you have any feedback/questions
