Pannenkoek explains how Super Mario 64 handles wall, floor and ceiling collisions, including triangles, normal vectors, quarter steps and out of bounds. It is a detailed 37-minute technical walkthrough of the game's physics.
Praised as an engrossing, in-depth look at SM64 mechanics that is surprisingly compelling to watch.

That's nothing! He has two videos on walls, floors and ceilings, each longer than half an hour (and both of them extremely interesting) Part 1: ▶ this video Part 2: link
Pannenkoek just released a glorious 37 minute video on sm64 mechanics: ▶ this video And if you have never watched speed runs, Summoning Salt has a fascinating series on world record progressions in popular games: link
