Doubles Isolated Antispin

i so didnt undertand this thead & had a problem visualising.....

those pictues now have opend my eyes muchly..

i thought i had antispin almost down, but it seems not - so many patterns to play with! i now have a whole new level of doubles to learn YAY! thanks for being really smart geeky people

When i grow up i want to be like you

Meg - for the visual enlightenment - see you tomorrow!

exploded pentagon:

Mint Sauce shouts at me for doing hexagons and pentagons *sulk* He says i have to do stupid diamonds... just cos simian does diamonds...I don't know why he doesn't just marry Simian if he loves him so much....

So I was thinking about this on the train down to leeds.

The box anti-spin. The staff makes a box, or the hands follow the path of a box, or the wicks can follow the path of a box. (I don't think I've posted a picture of that one yet.) I think the box anti-spin I posted is more like a box isolation. and the wicks following the path of a box is also a form of box isolation. (Cos I can't figure out in my head how to anti-spin my arm in relation to the box.)

triangle should work out the same way:

anti-spin: your hands following a triangle.
anti-spin: the wicks following a Y / fluz capacitor line shape.
isolation: the wicks following a triangle.
isolation: the staffs making a triangle.

I made more pictures;

wicks tracing a box:



hands:



wicks:

oooh cool

of course, you could do that "box wicks" pattern with a true antispin circle rather than a curvy diamond, just like you pointed out with the "cross wicks" pattern

and mr cantus, you can tell tobi that munky says 3-point or 5-point antispin is equal in validity to 4-point antispin, and greater in difficulty.

I'll have to draw a picture of the curvy diamond cross anti-spin in order to understand that. Does it depend on the size of the pattern in relation to the staff?

meg - both methods of shape isolation are related to staff length.

the main difference being that the longarm versions depend on your arm length in relation to the staff length/pattern too.

"to get the isolation to work in both dimensions (horizontal and vertical) using a long arm circle, it is necessary for your stick to be *exactly* twice the length of your arm (from shoulder to palm)."

I was thinking... it'd be nice to have a short-form verb for:
"rotating an object and manipulating the centre-of-rotation in such a way as to produce strange, interesting or startling patterns."

cos at the moment people are often using "anti-spin", which is really quite a particular definition, and doesn't cut it. Particularly if you're not manipulating the centre in a circle in the first place.

something related to the op-art movement would be fitting, as the aesthetics of anti-spinny business are very similar.

we have to think about this carefully.
It can have TERRIBLE ramifications if a bad name is chosen.
For example, see "Wibbling"
*shudder*

<appears out of the wings in an evil villian disguise>

what's that you say simian? We should call all this weird pattern stuff wibbling?

Aaaaaaaaarrrrrggggghhhhhh Nooooooooooooooooooooo!!!!!!!11!1oneone!!!!

*leaps out of nearby window*

the problem is that your long description doesn't really cut it either monkey...

taking just the circle-circle relationship we have this:

"patterns that are produced by following a point rotating on the circumference of a circle, the centre of which is rotating about the circumference of another circle"

this is called 'epicyclic motion' and was invented by ptolomy to describe the retrograde motions of the objects in the night sky - he was a bit of a geek you see but i'm sure we can all relate.
we call these compound circle patterns because that's what nick called them and that's exactly what they are - hence, the name makes loads of sense.

there is then the special case of epicyclic patterns where the relative rotations of the two circles are opposite to each other - this is the technique that we currently refer to as 'antispin'.

so, we are now at a point where we are particularly interested in those antispin patterns that are not composed of two separate circles but rather a circle that moves on a path that can be any pattern at all.

we have three choices:
1. an addendum to 'antispin', which implies that the motions made with our hands are something other than circles (irregular antispin?)
2. extend the concept of antispin to encompass this wider definition
3. make up a cool new word that sits above antispin but below compund patterns in the hierarchy of terms

i would say just go for number two (with a little number one if its really required).


having said that, i think the word 'retrograde' rocks

if we have to use yet another word to describe these patterns, that's the one i like.

it not only sounds cool but it actually has something vaguely to do with what's going on in the patterns.

"that's some sh!thot retrograde spinning you got going on there"

"that's a retrograde pattern i've never seen before - what are the component patterns?"


epicyclic -> opposite rotation epicyclic -> non circular epicyclic

compound pattterns -> antispin -> retrograde

incidentally, i love the sneaky little double sided triangle pattern you threw in here:


it's proper wierd.

you can really mess about with it's dimensions to produce a bunch of different pattern versions.

i think my favourite being the one that looks like a giant sweetie
(positioning the horizontal staff from the "low" section above the middle of the pattern, and the horizontal staff from the "high" section below the middle of the pattern)

and of course, there's no reason to stick to symmetry when messing with the patterns.

well, apart from aesthetics, but who really cares about them anyway?

I like the word exemplar, which has roots in the latin word exemplum which means 'pattern'. plus from http://en.wikipedia.org/wiki/Exemplar, it's also a second meaning as a standard problem to be solved... which is really what anti-spin is...

unfortunately, I couldn't really imagine myself saying it in real life.

Nor with retrograde, though it does sound cool. (cos some of these patterns are isolation based, not anti-spin based.) Unless you just tell the ones that don't fit in to just [censored] off..

oooh, i found another cool word that describes a bunch of these patterns, including the curvy diamond:

hypocycloid

anyone know where on the web i can find one of those cool java-based hypocycloid generators...?


cole. x

hands follow circle, staffs tries to make a square...



naturally you could move your hand in a circle and get the staff to follow an expanded circle.

Hypocycloids rule! That was the best google image search ever.

i want to spin this:


and i'm so using that name now, and don't care whether anyone else ever does
