I'm a little at a loss for what to say about this video, except to say it's fun and very cool. They (Marginalia Project) are playing with a video technique, and I pulled some description of what it is from their website, pasted it below.
Chronotopic Anamorphosis from Marginalia Project on Vimeo.
Their Description of what you're seeing: The image is digitally manipulated by fragmenting it into horizontal lines and then combining lines from different frames in the display. The result is a distorsion of the figures caused by their motion in time, or, as Brazilian researcher Arlindo Machado calls it: chronotopic anamorphosis.
The effect was completely based on Zbigniew Rybczynski's "The Fourth Dimension", but transposed to Processing programming environment and performed in real-time.
The software still has some memory issues, specially when the image rendering is combined with video recording, as it can be seen in this video.
