Sorry, it too me a while to get around to reviewing the suggestions here. I just watched [1] and found Kate's style quite impressing. For instance, I loved the analogies she used (the weird complicated statue, the simple metal ball, the legos) to convey what she means by simplicity], as opposed to what people would normally think "simple code" would mean. I think this is not too different from how great presenters sometimes use cultural references, even memes, to tell a mini-story about their ideas.

Thanks for mentioning her - I'll definitely watch more of her talks.
