Movie 1.

The demo is based on a painting by van Gogh “Wheat field with cypresses”. There are five parts. 1: The painting is shown without any intervention. 2: The painting is tiled. Each tile is filled with a randomly shifted copy of what “should be there”. Random shifts are drawn anew for each frame. Notice the turmoil which looks much like a continuous deformation. Occasionally one spots the edge of a tile, though this requires some scrutiny. 3: Like 2, but here we introduced “cracks” between the tiles. The impression is not that different from that in 2, although the movements seem confined to the tiles. Occasionally one believes to see the tiles themselves moving (which they don't). 4: As 2, but here we introduced flashes between the frames. Notice that the impression of a continuous turmoil is gone. One notices occasional dislocations between the tiles. 5: As 4, but here we have both the cracks and the flashes. The major impression is that of a coherent image. Some scrutiny reveals occasional dislocations. The contrast with the impression of turmoil as in 2 is very striking. Please click to play.
