A small experiment with slitscan

I've spent a lot of time over the last few days thinking about how time is used as a sculptural material in Zbigniew Rabcynski's work The Fourth Dimension. Watch it here, I'll wait.

I decided to have a think at how I would approach a dynamic slitscan film.

Here we have a perfectly looping video - made in Processing - of the Venus de Milo rendered in pleasant pastel shades which fills a 360 frame buffer. It could have also been 255 for pretty obvious reasons. The pattern image is rendered in black and white and for each image in the pixel array the white value is measured and the same pixel from the image in the buffer that matches that position (image[x][x,x]) is added to the new output image. You can get some really interesting effects from mixing video sources or even feeding an image back into itself as a temporal offset pattern.
