                This webpage is an interpretation and continuation of the printparty Up Pen Down, performed at Balsamine Theater as a part
                of Saison des Cultures Numériques 2017. The performance was the first public moment of a research focused
                on that which is between digital type design and bodies. Letters and movements, dance notation and programming,
                digital codes and coded physical gestures, plotters and body parts interacted with each other and blured
                the distinction between choreographic and digital practices.

        <h2>Dialogue</h2>
        <p>
            <span class="name">Pierre</span> Maybe imagine a human having a perception of a vector for the first time: a pregnant woman walks
            on the flat surface of a beach, to the background of the sunset. She hunts birds with a bow and an arrow. As
            she bends the bow, she feels how its straight rope interacts with the sturdiness of the bones of her arm and
            how the curved wood of the bow is in sync with the fibers of her muscles. All those straight and curved lines,
            along with the soft arc of her thick belly, are also drawn by the sun as her shadow stretches on the sand. She
            launches the arrow. The arrow itself could be seen as a vector-wave-movement. She also feels how rays of sun
            project her transformed shape of her shadow on the sand, following another straight line. She looks more closely
            at the border of the shadow, and sees the very moment where some grains of sand get lightened by the sun, like
            many corpuscules-pixels-bitmap, envisioning in simultaneously the two main components of digital images, and
            t two ways of describing tangible matter.
        </p>
        <p>
            <span class="name">Pierre</span> There are two matters within the digital, the molecular, which we recognise as bitmap and know
            very well, and the ondulatory – the vectors. I want to not only utilise vectors, but also to go anthropological
            about them. From that perspective I can tackle what is important in the aesthetics vectors create, beyond what
            things look like and into the way they operate and influence our own operations.
        </p>
        <p>
            <span class="name">Ludi</span> I have the need to include the body in the investigation of digital typography, because through intimate
            relations with vectors, we can trace back histories of writing that depended on the body and its movement.
        </p>
        <p>
            <span class="name">Ludi The body has its own intelligence. When I put, for example, the tension of the curve into this awkward body,
                some aspects of the digital practice become apparent in a way that I can't put the finger on, but I feel
                that only the body can detect.
        </p>
        <p>
            <span class="name">Ludi</span> OSPies like dancing. But we do end up sitting on a chair when ever we deal with type design. Its
            maybe a fantasy to think that such different modes of being could come together in an interesting way, but here
            we are, using one practice to reflect on and activate the other.
        </p>
        <p>
            <span class="name">Gijs</span> With Metapost, the human becomes the choreographer and the machine is the dancer, interpreting and
            improvising with the score.
        </p>
        <p>
            <span class="name">Gijs</span> Actually, a vector is a meta picture. Only when rendered it becomes a shape.
        </p>
        <p>
            <span class="name">Adva</span> So, could we say that vectors are like movements?
        </p>
        <p>
            <span class="name">Gijs</span> Yes, in this case the movement is a rendering device.</p>
        <p>
            <span class="name">Adva</span> Maybe both movement and vectors are potential, actualised through rendering processes, by the body,
            by the machine, by anything they activate?
        </p>
        <p>
            <span class="name">Pierre</span> I find both dance and graphic design poetic practices, but sometimes I felt we killed their poetry
            by forcing them to interact with each other.
        </p>
        <p>
            <span class="name">Ludi</span> We slowed the rendering process down so much in order to look into the process it facilitates. Maybe
            that's what killed the poetry?
        </p>
        <p>
            <span class="name">Adva</span> I find poetry in the fact that we sometimes look at those technical processes through the perspective
            of movement.
        </p>
        <p>
            <span class="name">Gijs</span> If you think of programming from the perspective of movement, for exemple loops, the time it takes
            to execute the code, the electrons jumping, freezing, flowing, interacting through the processor - all become
            interesting in a different way.
        </p>
        <p>
            <span class="name">Adva</span> I understood at a certain point that Up Pen Down is not a linear research, but rather an environment
            we created for ourselves where methods, actions and questions we come up with can interact with pieces of art,
            of knowledge, of completed or unfinished explorations of others within the field. Up Pen Down is for me more
            of a place to be, than a well studied research question.
        </p>
        <p>
            <span class="name">Adva</span> By allowing different body practices to infiltrate one another, contemporary dance went through various
            exciting waves of new discoveries about movement. At a certain point the body withdrew and the conceptualisation
            of movement entered the field. I ask myself if there is something new to find about movement through looking
            for it within digital processes and if yes, can it maybe generate a new way of thinking body and of making dance?
        </p>en fait
        <p>
            <span class="name">Adva</span> I read once a Kabalah text about the letter . Sometimes this letter is used to indicate the name
            of god. In that case, it should be written, but not pronounced. Its not because it represents god, but because
            they believe that the letter itself, when written, contains divine power that is lost in the transformation through
            the body from the written to the spoken. I like the idea of a letter carrying its own agency. This story is taken
            from a mystical culture, but also on the more up-pen-downish level, we create texts, choreographies and technologies
            that at a certain point become existing in themselves and start a relationship with us.

                is still coming in. Equiped with different coloured technical tapes, each one coordinates in solo or binomial
                to place the different markers. The installation of the tape uses walking techniques inspired by the performance
                of Esther Ferrer

                filming next to it so that the audience can see the pen trajectory, plotter's dance projected on the side
