Love the animation. How did you create that?

Thanks for looking at my devlog and for the comment! It's actually not that hard with Unity 4.x and above, as I am utilizing the mecanim animation system that was introduced in Unity 4.0. What you do is take multiple animation clips, trim, align and loop them so that things like feet, arms, and posture are as close as possible, and then you can blend together the various animation data, creating new animations from the blending of the old animations. For instance, the dancing above is 5 separate dance animations blended together to create 100 variations of dance intensities. Then, when I generate a crowd of dancers at runtime, it's easy to randomly assign them all unique dance intensities so that the scene is varied and doesn't feature different NPCs all doing the exact same dance at the same time.

Here's a great tutorial on the subject:
