This relates to an issue I have been playing with, which will not
likely become a reality for several years, but then will become very
important. I call it REAL-TIME RE-FABRICATION. It means objects which are
fabricated in such a way that their configurations are not permanent, but
are subject to controlled modification. Think of a figure skater,
and all the many configurations she assumes in her dance. When she puts
her hands out in front of her, we do not think of her as a different
person just because the shape of her body has changed. But when we want
to change the shape of a model, we currently have to refabricate a new
model with the different shape. This is because current fabrication
techniques yield solid materials in immutable configurations. Future
fabricators will use smart materials and fabbed robotic mechanisms to
make objects that can change themselves without being built again from
scratch. This is what I call real-time re-fabrication, and it will be
analogous to the ability of software prototypers to change their models by
modifying a few lines of code.
