Trammel harmonics for staff and other spinning props

Buy my DVD here: http://j.mp/encyclo-poi-dia2 -

The Trammel of Archimedes is a device that can render all 1:1 antispin moves and 1:1 linear moves. I originally made this video to show MCP my ideas about the unification of all of these... and the harmonically proportionate elliptical paths that they all tend to follow.

This is absolutlely incredible

[AlienJon]

Thanks!

How did we somehow not meet at Fire Drums?! @_@

[WizzYo333]

It seems to me that most of these wouldn't be too difficult to perform with poi. Poi is just a broken flexible staff

[AlienJon]

Yup, depending on your poi's orientation to gravity some are rather challenging.

[AlienJon]

At 2:14 you can see a horizontal cateye!

;p

[AlienJon]

Hmmm, does youtube figure it out with punctuation directly after the time code?

2:14! 2:14? 2:14. 2:14, 2:14; 2:14: 2:14' 2:14" etc.

How about with a space?

2:14 ! 2:14 ? 2:14 . 2:14 , 2:14 ; 2:14 : 2:14 ' 2:14 " etc.

amazing

[haroldchode]

This is legit. Nice work Jonny.

[shmoofoobean44]

agh this gave me a headache...and an itch to pick up my poi again

[shadowcheets]

This is awesome. How patterns work always seemed like mystical black magic before until I saw this. Now a lot of concepts are coming together at once. Still got a long, long way to go before I have the skill to implement any of the ideas, but I'm still all excited about understanding this stuff more. Thanks!

[panchoavendano]

osome, where did you made that animation, i would love to do that whith my pois, but, it looks super hard

[AlienJon]

see, cool timecode link! So how is Australia Meg??

[AlienJon]

Of course some stuff is trickier with one prop than another. I cant believe I didn't think of Floating Swords for these!! Their weighting would work nice.

I think the nexus where 'stickies' cross (3/4) is interesting, and these ideas could uncover something novel. Of course I also think staring at my own hand is interesting and novel sometimes too! @_@

[AlienJon]

Concerning holding in different places: by doing so you change your range of motion and limits. Learning to do the same patterns held in different places will get you used to different hand paths that are harmonic with the shapes you already make. Then, all of a sudden you can bust out and transition in a different, unexpected way, due to different constraints. Lester does some cool staff, holding at about the 3/ points.

[AlienJon]

I concede that a cateye IS an expanded trammel... is a cateye... is a trammel... and yes, I do periodically go back and watch the LABs and curse at how I always find something that you already touched upon... like even 2 "unit circle" next to each other. ;P

In fact, now that I'm thinking about it, I really should take this opportunity to say: You're the bomb Meg, and well ahead of your time me thinks!

[AWOLLA]

I think it's easier to learn an expanded trammel by making the line your hand is travelling, one 'unit' longer, than thinking about traceing a unit circle in the middle, or getting a three quarter point to make some figure.

Lines are simpler concepts than circles after all. Similarly in trammel it's easier to visualise the lines rather than making a half unit circle with a 3/4 point. Which would be hard.

[AWOLLA]

oops, meg here logged in as someone else.

It's not a cateye, it's expanded trammel. :p Go look at LAB 1. :D

Sticks don't make the 3/4 points more interesting I think, nor does putting your hand on the 3/4 points. They only serve to make the patterns of the ends different.

Plus they'd be mostly very hard to do unless using swords or something differently weighted. (or indeed something flexible)

[AlienJon]

So yeah I agree with what you said about it being just a framework (and a confusing/abstract one at that).

And yes I should probably annotate the transitions as well. Thanks for the good suggestions! I'll get on that in the semi near future.

BTW, have you seen what's at 2:14? Its a cateye! (who's time code I can link to exactly!) At the end of a youtube url add this: #t=_m_s

ie: #t=2m14s

[AlienJon]

I think it would have been less confusing if the 3/4 points only showed up at certain points to illustrate specific proportionate relations... but I was slapping it together quickly to put a visual on what I was blathering about.

This presented a nice opportunity to experiment with annotations to try and clarify a confusing video.

[AlienJon]

Yes the 3/4 points are subtle and confusing... but wasn't antispin a bit confusing when people first started getting into it?... and all these antispin vs isolation hybrids? As people start understanding it and familiarizing themselves with the concepts it will seem less confusing. After all, people playing with "stickies" are already using those 3/4 points, but with out thinking of it like this. Maybe this will lead to some interesting ways of "hybridizing" stickies?!

[11mcp11]

I think you should annotate the transitions between states as well as pointing out useful bits of theory. Still not enamoured by the 3/4 point trails. Just confusing really, if you wanted to learn the patterns or otherwise.

Could point out that any/all of these ideas are just frameworks to break up the infinite space of possibilities for staff/prop movement. A framework has constraints that help you to understand more about the possibilities of movement, but they are constraints nonetheless.

[AlienJon]

Now also realize that at a given hand path, you can take all of the line-segment to be the prop, or you could just look at part of it. So take 1:36 for instance, if you look at the whole line from blue node to orange node, you see a horizontal trammel. However, if you look at only half of it, from green to orange you have a horizontal linear extension, or from green to blue, you have staff antispin. Granted, some of these are really tricky to approach with poi!

[NathanielEverist]

Nice, well I'll definitely give it a shot with some multi-ball contact stuff.

[AlienJon]

These are admittedly staff/baton/stick/club oriented. But you can think of it them in different ways. Think about holding the prop at each of the points, and how you will have to move differently to create the pattern... It should get people playing with different hand paths.

[NathanielEverist]

Ah ok, so this is all 2D, that makes it much more easy to understand :). I was thinking that some of those would be impossible because the person's body would get in the way. I'll have to try these, although some of them would be really hard with poi.
