Hi everybody,
I’m a very forgetful juggler and always have a hard time to remember how a particular pattern starts or even what would be an interesting pattern to
juggle. Now there are different sources, where one can look up patterns, but somehow all of them have some room for improvement, so I decided to try my hand at it and aim for some points I was missing:
* starting postitions ascertainable at a glance,
* nicely printable document,
* compact and exact representation of patterns,
* inclusion of new patterns.
The current state can be downloaded at [1]. Right now it is only a preview with just a bunch of patterns, but the technical side of it is mostly solved
[2]. Before going all out I would like to get some feedback whether this seems useful to people and what could be improved.

[1] Passing Anthology & Causal Diagram blank sheets
[2] It is a LaTeX document and all the graphics are done in tikz with a Lua script for generating causal diagrams.

[]I want to make sure that everyone knows that it is very easy to see from a causal diagram how a pattern starts.
The number of “extra” clubs each hand starts with is equal to the number of causal lines* that ORIGINATE in that hand as you read the diagram from the left. Add 1 to each hand’s extra club count and that’s the number of clubs the hand starts with.
For instance, common 6-club patterns have causal diagrams like this:
A: R …
X
B: R …
so each R starts with 1 extra club and each L with 0 extra clubs.
So each R starts with 2 clubs and each L with 1 — the common start.
When I draw causal diagrams, I usually include “wrap-around” throws at the start. They are throws represented by lines coming in from the
left with no originating hand shown on the left. The number of extra clubs a hand starts with is also exactly equal to the number of wrap-around throws TO that hand in the diagram.
Don’t like a given start? Cut off the first count of the diagram (onthe left) and evaluate the start again, to see if you like it better. Repeat until you find a start you like.
*To clarify for those not very familiar with causal diagrams, a causal line is a group of arrows connected through the diagram, with the end
of one arrow pointing to the beginning of the next arrow. Each throw in such a causal line causes (that is, forces) the next throw in that causal line. Hence the name causal diagram.
