 This uses the left grayscale movie as an index to look back in time, pixel by pixel, at another source movie. Black represents the current time, and white represents the current maximum delay, written at the bottom left. The resulting time-delayed movie is shown at right, yielding beautiful effects of many different time-lapses occuring simultaneously.

This project was inspired by Alvaro Cassinelli's "Khronos Projector". Here, I use premade movies instead of an interactive tangible deformation screen, allowing for more complex and quicker moving index matrices, and therefore more complex results. The source film is a public domain film of UK mass bike rides. Coming from an audio tradition, I was interested in the idea of a applying different time delays to each pixel; this now becomes a representation of four dimensions on a two dimensional screen. While I love the purely conceptual interest of the physics involved, it is my hope that, on the part of the user, a conceptual appreciation is able to interact with an aesthetic appreciation. This is a software process that I hope to make available for public use, hence its use on a non-professional web video.

Technically, each pixel value 0-255 of the left grayscale matrix is scaled to a delay of zero to a max value (usually one to two seconds, at 25 fps). The source movie is played, frame by frame, with a trailing buffer of preceding frames. A new frame is reconstituted from this pixel-by-pixel delay.
