How do I create heavily distorted environments?

Good morning everyone,
I recently was contacted by a client asking me if I was able to replicate similar effects found in this video. Unknown Mortal Orchestra - Multi-Love (Official Music Video) - YouTube
He wants to create a 3D enviornment experience for a song he wrote… But he would like the environment to slowly go trippy like ■■■ style… I told I’d do some research before telling him if it was doable or not but I couldn’t find any tutorial or info about making heavily distorded environments…
Is there a way to go that further through Post Processing Volume?
Thank you in advance!
