    Figure 8, an expansion on Wiper Harmonic

    many penspinners say that.
    all Wipers are only normal and reverse.
    but, I believe Figure 8 is not Wiper Harmonic ,and there are all 4 types of Wipers.
    maybe, Somebody thought that, too. rolleyes.gif

    1st half of Figure 8 Normal
    2nd half of Figure 8 Normal
    1st half of Figure 8 Reverse
    2nd half of Figure 8 Reverse

    today, 1st half of Figure 8 Reverse and 2nd half of Figure 8 Normal is called Wiper Reverse.
    but, i believe 2nd half of Figure 8 Normal should be told from Wiper Reverse, or they can't be notated accurately :(

    for example, Moonwalk Wiper, Inverse Wiper. huh.gif

    thanks. wink.gif

    Figure 8 = Wiper reverse > Wiper normal, but with hand reposition between wipers.

    that trick seems very similar to infinity.

    anyway, thanks laugh.gif

    I just see Figure 8 as a combo of two hybrids where 2 tricks are done together. There isn't a set notation for describing it right now though...

    Figure 8
    [[Wiper + Charge Normal]] > [[Wiper Reverse + Charge Normal]]

    I guess the differences between the wipers are not significant enough to demand for unique names to differentiate them. When doing Wiper Normal, in most cases, the 1st half of Figure 8 Normal is done, while for Wiper Reverse, the 2nd half of Figure 8 Reverse is used. I don't think there's a need to differentiate them clearly, since the variations are about the same tricks done with different positioning of the hand.

    thanks for your replaying.

    >Sketching
    can do figure8 without charge(or like motion), if hold a pen vertical at the start .
    by moving the hand ("turnning over" ?).
    (I may say crazy english...lol)

    and there is one more problem of notation.
    It's saying 2nd Half of Figure 8 "Wiper Rev" . huh.gif
    Because, It is said "Reverse", but the direction is "Normal"!
    (It is not visually problem.
    Suppose the spins are horizontal. 1st is CCW direction. 2nd is CCW direction, too!)

    So, 2nd should be said Wiper Normal in fact (if all wiper's types are 2).
    But the spin direction is normal. moving direction(?) is reverse.
    So, I believe that it is moonwalk. smile.gif

    Aren't you guys making this trick seem much more complicated then it is? It doesn't have any spins, just rotations. It looks to me like Wiper -> Wiper Rev with hand tilting, no more then that.

    @Jiro: rotating your hand does not change the trick. It's only because your hand is rotating that the Wiper & Wiper Reverse is swinging in the same direction. The pen is still rotating in opposite directions through the fingers.

    I thought someone may say such your thing.
    maybe, you think Figure 8 has visually spin direction.

    I can do Figure 8 without rotating my hand.
    not visually.

    Don't look Wipers' spins have only vertical spin.
    there are 6 by widely view.
    Vertical (both the thumb and Index are side), Normal & Reverse
    _they had not thought to today_ (english?)
    Horizontal (the thumb is upside), Normal & Reverse
    Horizontal (the thumb is downside), Normal & Reverse
    (1st half of Figure 8, the thumb is upside, the index finger is downside.
    2nd half, the thumb is downside, the index finger is upside.)

    have a widely view. happy.gif

    It doesn't matter. It's similar to comparing a Sonic done palm up and the same Sonic done palm down. The direction is different only because of the hand position.

    JIRO, I completely understand what you're talking about. I was about to raise the issue about the 'vertical' Wiper until you mentioned it. Indeed, there's a different apppearance for the variations. But when we differentiate tricks, we have to look at the movement of the pen with respect to the hand or fingers, not just from our eyes. If you look from that perspective, you'll realise that the movement of the pen in the different variations of Wiper which you raised are actually the same. If you look at the thumb and index finger as forming a boundary, the Wiper Normal is just moving the COP of the pen from above it to under it, whereas the Wiper Reverse is the opposite. Since their basic motions are the same, we don't need different names for them.

    I had a exam in my school. and I have no more idea lolol

    hmm.
    I found that a thing I wanted to say.
    Wipers normal, in 1st half of Figure 8 Normal and 1st half of Figure 8 Rev, are different in the ways of spinning.
    so, it is not as palmdown(i said?)

    really, I have no more idea. wacko.gif
    thank you all.

    I'm guessing you're trying to say that those variations spin in different directions. But, again, you made the mistake of viewing the trick from above. If you hold your hand in front of your face, palm down, the variations spin in the same direction: anticlockwise (right hand).
