I have started to make footage for a new video which will feature swirl flo-viz. Here’s a clip from yesterday.
The swirl and reappearance of the coloured vortices as they move round gives this kind of visualization a periodic, rhythmic quality. Even as the colours begin to mingle we can still follow individual shapes as they complete their circuit. There are echoes of man-made objects, like the sweep of a clock hand, as well as large-scale phenomena such as the revolutions of planets and moons.
