It seems to me that a dynamical geometry program exemplifies information transfer without energy. For example, imagine a horizontal line with two points. One point (O) is fixed and the other point (A) is movable. Constuct circle which is centred on point O and such the circumference of the circle passes through A. The circle intercepts the line at a second point B. If the point A is dragged left or right the radius of the circle increases or decreases and this motion instantaneously changes the location of point B without a transfer of energy. "Dragged" is used metaphorically so no inertia or forces of any kind cause the point B to move in the opposite direction of point A. One could say this is just an exercise in abstract geometry which does not represent the "real" world, but why should such geometric relationships be excluded from the domain of what is real?
