the string is going to be attached at different points in the room so there will
also be tone
differences there; visually it is going to"barricade' the space and the part
where it could
break is actually a big part of the installation.
i'm not quite sure yet on how i actually am going to set the string in motion,
but i've tried
some different things and thats not the hardest part.
the basic big problem is the string pulling thing; i'm going to look into this
deeper with an
industrial designer, my knowledge just stops at a certain point there..
but what we've discussed allready is a combination of a gearbox and maybe a
string
tensioner.
the whole idea is off course to get the torque down somehow, and then also
somehow get
some sort of feedback on how hard it is being pulled.
we are going to look into maybe use the mc inlets and use some sensors to get
sort of a
feedback of the pull amount; i program the whole installation with max/msp and
use
softvns for motion tracking so if i can get information into max i can do
anything with it.

i'll keep you all updated!
