It's nice how it breaks down the patterns, and explains everything step by step.

If you would like 3D in-browser animations of a subset of passing patterns, you could look here: https://passist.org/patterns These only have terse generated explanations, because they all follow a common theory, which is https://passing.zone/4-handed-siteswap/

There's a community of jugglers who pass clubs who now document their new patterns with videos (and notation) at https://passing.zone/ rather than making animations.

For another "library" of sorts, here's a rather random assortment of (mostly) juggling related documents: https://jugglingedge.com/pdf/
