If it's TokenTown, then it's my project :) There's no skill file AFAIK, at least I didn't create one.
FWIW, my comment may have come off as more dismissive than I meant--it's a cool approach. I'd just never seen a visualization quite that like and then ran into two in the same week.
BTW I created a skill in the end for this type of animations: https://github.com/LaurentiuGabriel/learnscape
