Molassograph (1998)
In Molassograph (1998), the speed of moving particles is proportional to the luminance of their location's corresponding pixels in a live video of the observer.
Molassograph was developed for John Maeda's "Numeric Photography" course at MIT Media Lab in Fall 1998, and originally published online in a Java applet version at https://acg.media.mit.edu/courses/mas....
