This reminds me. The best "presentation" I've ever seen (and I was lucky to be present in person for this) has been by a guy that was, if I remember correctly a top person in Twitter's scalability team a few years ago. His name was Raffi. It was so good that I've since been looking for these slides actively and never managed to find them. The talk was about how they scaled Twitter after it became a thing, and what happens to a tweet once the user clicks "Post", how the timelines are generated, etc. The presentation on the wall was made so tastefully, and clicked so amazingly in place with the speaker's verbal story, that everyone was completely mesmerized. If anyone can find me these slides (they weren't traditional slides and the whole thing felt more like a smooth movie almost), I'd be extremely grateful. Great material to learn from.
