I’m sure you are already aware of this video, but for those who are not: https://m.youtube.com/watch?v=kpk2tdsPh0A this video is an amazing exploration of the various ways speed runners will use glitches to their advantage.
He recently did another commentated video, I believe maybe the first commentated one since that legendary video, on pendulum manipulation. https://youtu.be/nYDmBdUalgo
It may be a bit slow for the types here already well familiar with floating point and the like but it's still got amazingly deep content on something silly but fun.
Gosh, I must have watched that sleep-deprived a very long time ago last night, but I will have to take another look at that. So many views. Foggy memories, I think I remember seeing this.
In any case, yay amnesia! Worth seeing again for the half-first time. ;PPPP
I actually rewatch this video a few times a year. I just love everything about it so much. It is a well taught physics lecture for a system of physics that was created by people.
For anyone who thinks they might enjoy "speedrunner overcomes all the odds" narrative style videos, I've greatly enjoyed the content of "ThaRixer" on the topic:
He gives a good sense of how unlikely it was for some of these glitches to be found, and how much luck and skill is involved in pulling off a successful world record.
