Watching the exhibits at the opening last Thursday, not as a practitioner
but as an interested party (I am a poet), I was struck by two things
particu;arly: first, the mesmerizing effect many of the constructs had on
me. That was not very surprising to me because I was aware
images,particularly repeated and detached from words, may have that effect
(I did not use any of the ear phones, basically because I couldn't hear
wear through them). Nevertheless, it occurred to me that perhaps in digital
art that Mesmer-ly effect occupies an essential part, as in photographs. I
do not know whether this is entirely true. I only want to say that this
effect is different from illusion. It is rather its opposite, decomposes
illusion and points to something illusion hides. A machine perhaps, again
like the photograph, to dis-cover the uncanny.

The second effect was perhaps more powerful. Looking at *some* of the
works, I had a sense that the creators were aware that they were bringing
images into existence for the first time, creating new images. Once again,
these images were not illusions because they were not copying or
representing anything--except as the projections of the mind. I sensed a
medium that, properly used, can be the medium for a new kind of
subjectivity; not particularly of feelings but of thought. Because of that
the two graphs comparing how the insertion of the "computer" affected and
altered the previous channels of communications constituted one of the most
powerful images in the exhibit.

I also would like to comment on something that I think Jason said. To call
cinema a medium that creates illusion is too general and not correct. One
should just think what Godard may have meant when he said "cinema *is (not
imitates)* life." To consider the lens to be a medium of reproduction is
totally to misunderstand it, something many people during the origin of
photgraphy did. The lens, as an optical robot records things that the naked
eye misses. That is its originality as a machine.

> For those of you who are not familiar with this device, the Paik/Abe
> Raster Manipulator (aka the wobbulator), was first constructed by Nam June
> Paik with the guidance and expertise of video engineer Shuya Abe in the
> late 60's. I am not sure why it was eventually called a wobbulator, but for
> some reason I imagine this is a term that someone like Walter Wright
> probably coined (sounds like him). Simply put, a wobbulator is a modified
> television that has a series of larger TV yokes and hand wrapped copper
> wire coils that are placed in certain areas of the back of a cathode ray
> tube so that when voltage is fed through them, they become electromagnets
> that cause the raster to scan in wild patterns on the screen of the
> television. A good example from the Hunter exhibition is Marisa Olson's
> "Black or White", found here: https://vimeo.com/110210532
> Now, the reason I maintain this is an instrument instead of a prepared
> television like Paik used for works like "Magnet TV" is the ability to
> visually articulate a wide range of "notes" from which the user could
> "play" the unit. The traditional unit had three basic functions: S,
> Hotizonal and Vertical. All of these manipulations could be controlled by
> the frequency of the audio or control voltage being fed into the coils of
> the unit, so the range of what you could get out of a wobbulator is as
> broad as you could get out of audio synthesis (which is to say, a lot!)
> The wobbulator for this exhibition was created in the spirit of the unit
> that was used by most of the people who came through the Experimental
> Television Center. It is created from a Sony TV 760 television from 1967,
> which was one of the early portable TV's that Sony made. I did leave out a
> couple of features, such as the raster collapse/reverse switch, for
> logistical reasons so that the gallery staff would not accidentally burn
> the screen of the unit and to keep it relatively simple for them to set up.
> Otherwise, most of the hardware is similar to what you would have seen on
> the unit at the Experimental Television Center, except that I used a new
> method that Dave Jones and I came up with over the summer for the
> vertical/horizontal deflection. The TV's center's unit had a dolor
> deflection yoke from a TV from the early 60's that would be used for
> horizontal and vertical deflection. The problem with building this today is
> that there are very few of those tv's or those size yoke available anymore.
> So, our method we created this summer is a technique to use modern yokes by
> detaching them from their housings and clamping the new yoke from the side
> rather than having to slip it over the back of the CRT tube.
> Technical details aside, the unit  that I made for the exhibition is kept
> behind glass for safety reasons. So, to generate the signals I simply
> created a program in Max/MSP/Jitter that phased the S-coil and vertical
> coil signals to be offset from one another with ramping values from 58-62
> hz in order to show variability in the image manipulation. A 60 hz sine
> wave will create the effect, but it won't move very fast, so having small
> changes brought out the dynamism of those coils. The signal was also being
> brought up and down in volume, which affected the intensity of the process
> and also leaving some "breathing room" for viewers to be able to see their
> unaffected image on the screen and watch it ramp up and be ripped apart by
> the raster displacement. I then recorded these phasing changes for about an
> hour and burned the audio to a DVD and fed that into the amplifier that is
> running the wobbulator. I could have put it on a computer, but I wanted to
> make this as simple as possible for the staff at Hunter to deal with since
> I was not there to set the unit up, and I think it worked pretty well.

> mind you, just not necessarily the kind you might find at this exhibition).
> Special effects, to me, mean illusion. I think a better term to describe

> perception as truth, and in many ways all of the instruments used at the
