Time-Varying Lights gallery
Here is a selection of images of time-varying light sources. All were taken with conventional DSLR cameras; however, the camera was moved during the shot, allowing the lights to paint "traces" across the sensor. The traces show the history of what the lights were doing during the exposure, and hence, the time-varying behavior of those lights. The photography section on this website has more details on the technique.
