I figured it would be useful to start collecting a library of gifs for each signal. I know personally it helps me to see lots of examples rather than just the few in the codifier.
Here’s a place to collect gifs of the Fe - Coordinated Emphasis signal, which is described thusly: “The head and hands both gesticulate in the same directional axis and land their hits simultaneously."
The gifs don’t need to show just this one signal in isolation, necessarily – as long as the relevant signal is clear.
To start, here's two examples of Abby Martin, in the database as FeNi l---, displaying coordinated emphasis.
