Aronofsky Reimagines Swan Lake with Black Swan

I witnessed Aronofsky's  Black Swan back before the turn of the year,  It was angled to be a psycho sexual thriller about ballerinas with some super human overtones, along the lines of transformation.  After a month of being a stage hand for Nutcracker after Nutcracker, one would think I had enough Tchaikovsky or even enough ballet for that matter.  However, because Of  Pi and Requiem for a Dream I had some extraordinarily high expectations for this one, and by my first impression I was not disappointed at all.

 My tendency to judge films starting with the first frame was quickly annihilated by the long shot of a dancing ballerina that turned out to be Natalie Portman,  Her acting through out the movie continued to push boundaries and what impressed me most was her dedication and dancing as a ballerina.  Mila Kunis as the free spirited sexual dancer posed in a position between honest friend and rival for the glory of the Swan Queen was...well, Sexy.  Vincent Cassel also plays his role perfectly though I think his character merits some unfair judgment as the villain.  Winona Rider also delivers as the ousted former lead and serves well to cause no end to the angst of all involved.  The movie plays with psychology like clay,  Mirrors through out the story testify to changes real or imagined,  And truth hangs out in the edges to be viewed from a variety of visages.  Further twists in the story telling reveal, that the arch of the story line drifts out of a movie about competition in the world of ballet and deeper into the actual fable of Tchaikovsky Swan Lake. 

Coming home after it was over had left me struck dumb.  Maybe it was the jerky camera movements the graphic nature of the story, tangles of fear,  sex, repression, Fingernails, the pace of the trajectory, the quality of the music, or the sound and picture in the Archlight Theater in Hollywood.  I was wobbly kneed when I walked out, lost between real and delusion.  I literally felt high when I left the theater,  Like I popped MDMA with the girls in the bar. The film most definitely got under my skin and got my adrenaline going.  I was weary to write this lest I ruin any sort of surprise for anyone who has not seen it. Truth of the matter is I think I know what happened but I'm not sure. I am going to have to watch this one again to fully comprehend the brilliance that went into it.   Probably the best new film I saw in 2010. Well worth a view.

I would also like to mention in post script the way the Europeans handled the Art Deco promotional posters,   Very nice...

I thought Russian Constructivist or and then of the Nick Gaetano cover art for the Ayn Rand books.  Its really good stuff though.  Would to have loved to see this all over LA, really would have fit in over by Wilshire.  Some digging and you find out about LaBoca who this can be credited to.  So much good stuff out of the UK, but that deserves its own time and place.

However the chips fall...
Bravo to all involved with every part of this living piece of art that is Black Swan.

The Body as an Interface

Biomechanics is a rising field of interest for many different people from medicine to sports and even into the arts.  The human body can be monitored in a variety of ways from eegs which measure brain waves,  eogs to measure eye movement in sleep studies,  heart and breathing monitors. The depth of research into this world is an abyss that seems to be come ever deeper the more one learns about the subject.   My interest in the subject remains within the arts and with movement as a control of a non-clinical environment.   Our main limitation is that the human body can can only (as of yet) be interfaced superficially.   This leads to problems measuring human movement because joints which could be hard to measure on their own are even harder to access because they are deep to certain muscle groups and skin.  For a short example of the complications, take just the lower body from the superior structure the hips down to the inferior ankles.  By limiting possibilities to the larger movements of the skeletal system (particularly to those inferior to the transverse plane) you end up with only six large joints acting independently of all others. For monitoring, movement these joints can be looked at in 3 pairs of root sensor systems.

    - the hips
    - the knees
    - and the ankles

When standing, we can say that the body is at unity or the starting/natural state.    Most joints are in their natural state of extension in this position.  and then...

The Hips

When dealing with the hips circumduction becomes a problem because of the 3 Dimensional conic movement of a ball and socket joint.  The closest electronic analog i can think of is a joystick which measures potentiometers on two axis  and outputs both position values like coordinates (x,y). if we were to use a flex sensor we could only measure the anterior hip motion along the the sagital plane because of the gluteus maximus and hamstrings on the posterior which mask the small angle of movement we could measure if we had access to the acetabulum where the head of the femur makes contact with the coxal bone.  One might be able to measure the movement of the greater trochanter but that would still be difficult with the muscles which act as the flexors of the hip joint. This problem holds firm when you try to measure abduction(open) and adduction(closed) on the frontal plane as you would see it in Leonardo's  "Anatomy."
{as a side note measuring the medial and lateral rotation would be difficult as well}

The Knees

The knees being a hinge joint are the only joint on the lower body that can be easilly monitored using a flex sensor.   Hinge joints lend themselves to this type of monitoring because they have one state of extension and one state of variable flexion from 180 degrees all the way open down to about 10 degrees as folded as possible.  Flex sensors aren't really useful for any other type of synovial joint.

The Ankle

Measuring the ankle is weird because its natural state of extension lies between two points of flexion: dorsiflexion with the toe up and plantarflexion with the toe down.   One could put flex sensors along the achiles tendon and the dorsal part of the foot where the tibia and fibula meet the talus.  

More of the foot could be wired up to flex sensors for each of the phalanges and metatarsals but the shoe probably wouldn't be very comfortable.  For the foot I would like to develop some sort of measurement device that would be more intricate but similar to the type of system that you see in children's flashing led shoes.  the system would have quite a few pressure sensors embedded in the soul of the shoe to measure the anterior most end of the metatarsals through the phalanges and cuboid area and also below the calcaneus to measure the weight displacements as a user moved and balanced in different ways. 

So you see talking about the body could get complex, let alone measuring it. Then there is a whole new slew of fun to be had by all.  So the knees and elbows are easy bend sensors,  and then... fubar...

If you like the flexion measuring its worth a look at the MidiDancer developed at CalArts by Coniglio and Stoppiello of company Troika Ranch.   That's where it has all already happened in dance... has been happening since 1984...probably longer... at the risk of repeating the grand. 

I had original aspirations to use such a system for performance after having my brain fully warped by the book "Machine Musicianship" by Rob Rowe.   It was Morton Subotnik's work "Intimate Immensity" and his use of infra-red beams in a system technically executed by Clay Chaplin and danced by Nyoman Wenten that led me to CalArts in the first place.  My exploration of sensor possibilities for retrieving information from the human body began with the use of video to track motion, followed by research into things such as joint angles and rotations, muscle stretch or tension, and pressure for weight displacement on the plantar surface of the foot. 

anyhow...

In my search for better sensors I came across some interesting developers and their websites.

Poleema sensors use magnetic feilds to determine location.

The porcupine is made of several tilt / ball switches which recognize motion and orientation on the three planes, it could be quite useful.

I also found a similar sensor that reads full 3d motion and comes with software(very cool).  www.xsens.com.  It uses small blocks which could be fitted to the femur and the tibia/ fibula and would send out information about the orientation of those bones.  Really, useful stuff it also says how fast it moves etc.. check it out.

Also, there is a book called "Three Dimensional Analysis of Human Movement"  containing essays of many different scientists edited by Paul Allard. 

Its something to think about...more...
