On the visual miracle of "slit-scan" video

Hashimoto Baku ('a Tokyo based video director/visual artist/developer') digs into fascinating depth on the 'slit-scan' technique: '[imagine] a quite thick flipbook that all frames of a video are bound page by page. If you just rifle through it, the original video will be just played. Slit-scan intrinsically means slicing the flipbook diagonally.'

Applied to digital video, this 'means displacing a cross section of 'world volume' (like a flipbook, it is an imaginary 3D cube consists of 2D image + 1D time) along with 'time axis'. Part of time displacement whose cross-section is planar is so-called slit-scan.'

The effect is to make things stretch, distort, shrink and produce landscapes that are reminiscent of Inception.
