The Archer's Paradox in Slow Motion [video]
There's a scene in "Brave" (the animated movie) where you see Merida fire an arrow. The scene is rendered in slow motion and you can see the arrow flex as it leaves the bow. I knew that arrows flex as they are being fired, but this was the first time I had seen it in slow motion. Comparing what I saw in the movie with this video suggests to me that the animators did a very good job of getting this detail right.
