I'm a pretty late in realizing this, but Cosmo Wright, video game speedrunner, has performed a near-optimal run of The Legend of Zelda: Ocarina of Time, in 18:10.3. He's made a pretty educational and touching video of the gameplay with commentary on speedrunning, the history of speedrunning OoT, explanations of glitches and optimizations, and the like. It's a beautiful watch if you're familiar with speedruns and a very accessible/educational watch if you're not, so I highly recommend it.

I've never done speedruns or anything, but it awes me to see such a good run, and in some ways saddens me that it will be near-impossible to improve in the OoT Any% category now. Of course, that's been said before. It may take a few years, but I hope some new glitches are found someday. Well done, Cosmo.
