There's certainly the possibility for more tricks to be discovered. The problem is that OoT has been around for so long, that many tricks have been found and more or less fallen to the wayside in favor of tricks useful for speedrunning. ZSR's main site is no where near a complete compilation of every single trick or glitch, as there's more than a thousand tricks that are known.
I think I may have done this before, can't remember though
This is known (and a video reaching the fishing pond was made. However, I haven't been able to do it myself. How do different slopes determines how fast you drop, and how can you reach the pond?
This may also be old, but I don't think I've ever heard of anyone trying to swim in that dinky puddle.
Sorry about long descriptions. I'm also a programmer and I get very detailed, and this is an edit, so I'm sorry again for doing it in this post as well.
Lols, yeah, swimming in the "dinky puddle" was a rather random decision wasn't it, though I couldn't literally swim in the completely on map parts of it as the ground beneath it would just make me walk like normal but I can swim under it and in the spot I mentioned that protrudes upwards where the plank meets with ground, as in that case, there is ground above me and around me, but not below me.
Sloped ground effects speed of the fall because the deeper you dive the faster it wants you to rise to the surface. You can't dive on too slanted a slope or can't dive down from mid-air because it makes you "surface" and you don't get stuck "rising". But even so, even the slightest difference in slope between two spots makes a huge difference. (All the following assume starting fall from roof of lab in lake hylia) On a flat surface it falls so fast that it even starts picking up speed while falling. On a fairly sloped surface you can go significantly farther and it won't pick up speed whilst falling. On good slope you can make it to fishing pond thing like in video. On a perfect slope you could go over the fishing pond thing and OoB. With that kind of fall you could start off from height of the lab, and hang over the spot where magic leaf is, and you could go take a dump and come back, and you still won't have touched the leaf. With normal fall from roof of lab, it only takes half a second to land on leaf.
The camera lock was largely luck by performing all the said glitches and accidentally walking into water, I noticed the camera thing. Then piecing together the reason why it occurred was simple. Though I don't entirely understand the logic behind it as I don't know how they coded it exactly, but the combination of the behind the back camera and diving state caused it for sure. The interaction with water surface even when I was wearing iron boots must of made it want to adjust my camera to "surfacing" due to the "rising" state but because I had my camera behind the back and how I was still walking normally it tried to maintain behind the back camera but got stuck in some conflict between them. The result was that the camera got completely stuck in place when I touched the water surface at a depth enough to start swimming. When I walked back out, it allowed the camera to follow me again, but kept the bugginess of the conflict.
