Light Paintings

Photographer Stephen Orlando uses programmable LEDs to create light paintings. Here floating LEDs illuminate a track down a waterfall. In flow visualization terms, this is a pathline because it records the trajectory a particular particle followed through the flow. Streamlines, streaklines, and pathlines are all important concepts for interpreting fluid flow through visualization. To see more of Orlando’s light paintings, including some wonderful portraits of canoeing and kayaking, be sure to check out his galleries. (Photo credit: S. Orlando; via Colossal)
