jim's feasts for three jugglers
Aidan
three person Jim's two count feast. Suppose Aidan, Lynne and Caspar are
standing in a triangle. Aidan's sequence is Lynne self Caspar self self.
Lynne's is Aidan self self self Caspar self. Caspar's is: self self Aidan
self Lynne self. This is a normal two count feast. But if Lynne throws
crossing passes and Caspar throws crossing passes to Aidan you get a Jim's
two count feast. It's quite a nice pattern.
A natural question is can you do a similar thing with three count or one
count. When I first tried working this out i came to the conclusion that
you couldn't. Last Thursday, Des, a Jackson's jugglers alumni, came back
to visit us in Highgate. I told him about this pattern and how you
couldn't do a three count version. However afterwards I wondered if I was
right in saying you couldn't do a three count version, so when I got home
I tried working it out again and found one that worked. Likewise for a
Jim's one count feast. When I tried working out a Jim's pass pass self
feast though it didn't work out!
A couple of days later I aslo though of a Jim's inverted bookends feast.
So this Wednesday at Camden I tried doing the Jim's three count feast with
Matt Ab Tracey. As ever, when you're trying a new pattern we kept making
mistakes, but eventually it settled down and it seemed one sided. I tried
to watch what Matt and Tracey were doing, but it's difficult in the middle
of the pattern. Anyway we gave up and tried the Jim's inverted bookends
feast, which worked fine.
On the tube on the way home I tried working out the Jim's one count feast
and it came out one sided too!. When I got home I searched for the scrap
of paper where I first worked out the Jim's three count and Jim's one
count feast, to see what I'd done wrong. But there was no mistake, simply
a very subtle difference from the Jim's two count feast. For the three
count and one count versions Aidan crosses and Caspar throws crossing
passes to Lynne! A Jim's pass pass self feast works like this too, but the
Jim's inverted bookends feast works like the Jim's two count feast.
Have fun,
Aidan.

We've been doing this for several years at Stanford. We call it
Rick's Picnic (Rick Rubenstein came up with it). In any pair of
people exchanging passes, one is passing straight and the other
diagonally, so collisions are generally not a problem. Works with any
number of people, any count, and has some very odd sequences of
throws.
Here are videos of 5, 4 and 3 people doing Rick's Picnic in 3-count,
3-count and 1-count (one of these has instructions):

Thanks for the videos Martin. It looks like they're slightly different to
the patterns I described, but they're very nice and as you say generalise
nicely to any number of jugglers. So what's the difference? In your
patterns as far as I can make out each juggler passes straight on one pass
through the circle and then crossing on the next pass. In the patterns I
described one juggler is always passing straight, one always crossed and
one straight to one person and crossed to the next.

I've added somemore diagrams to the above links. Also I've made links for
three count and one count versions:

Each three person Rick'spicnic has two variations, depending on whether
the first person to make two passes throws straight or crossed. Also the
Jim's feast patterns have more than one variation.
Don't know if anyone else is interested in this stuff but it's kept me
occupied :)
