From Henri Bergson’s The Creative Mind: An Introduction to Metaphysics:
…let us imagine an infinitely small piece of elastic, contracted, if that were possible, to a mathematical point. Let us draw it out gradually in such a way as to bring out of the point a line which will grow progressively longer. Let us fix our attention not on the line as line, but on the action which traces it. Let us consider that this action, in spite of its duration, is indivisible if one supposes that it goes on without stopping; that, if we intercalate a stop in it, we make two actions of it instead of one and that each of these actions will then be the indivisible of which we speak; that it is not the moving act itself which is never indivisible, but the motionless line it lays down beneath it like a track in space. Let us take our mind off the space subtending the movement and concentrate solely on the movement itself, on the act of tension or extension, in short, on pure mobility. This time we shall have a more exact image of our development in duration. (165)
I wonder how Bergson’s meditations on time and free will would have played out had he been able to mess around with the Khronos Projector, a time-spatializing Processing sketch by Alvaro Cassinelli. This online instance is a stripped-down version of Cassinelli’s 2005 installation:
The Khronos projector unties time and space in a pre-recorded movie sequence, opening the door for an infinite number of interactive visualizations. Using the Khronos projector, event’s causality become relative to the spatial path we decide to walk on the image, allowing for a multiple interpretation of the recorded facts. In this sense, the Khronos projector can be seen as an exploratory interface that transforms a movie sequence into a spatio-temporal sculpture for people to explore at their own pace and will.
