Impossible Piano Physics Simulation - In the Hall of the Mountain King | Black MIDI

I built a simulation in Unity to visualize black MIDI files with physics! Every note note is a rigidbody which magnetically locks into position, presses a key, and spawns a glowing orb. This project pushed my abilities (and my PC) to the limit. The first portion was recorded with raytracing, so be sure to view in 4k resolution.

Fun facts:
- Thirty two gigs of RAM was not enough to hold the required game objects in the scene, so I upgraded to 64 just to make this video.
- Each frame was taking so long to load it was causing my GPU drivers to time out and crash. I had to edit a registry value called TdrDelay to resolve this.
- The final image sequence recording was over 100GB. Good luck youtube compression haha.
- My computer was rendering nonstop for over a week to capture the ray traced portion before the crash.

I believe this MIDI file was created by a user named @Sir Spork. Unfortunately, it seems they have deleted their YouTube channel, and I can't find a link to properly credit them. If anyone has a link to Sir Spork's social media, please send it my way so I can give the credit they deserve for this amazing MIDI arrangement.
EDIT: I think this is the new channel: https://www.youtube.com/channel/UCTLel5dQNhVuEGtqDM_Nu8Q

Huge shoutout to my friend Colin for building the Patron plinko at the end of the video. Here is a link to his channel: https://www.youtube.com/channel/UCfoV9j8kQzk6Ia0w19Px0iw
