I have never seen that before from anything other than the rear wing endplates. Have you?

Visible vortices from the sidepods.

I've never seen them before either, fascinating! Especially the Red Bull one coming off the front wing... Perhaps it's ectoplasm.

Vortices off the rear wing are quite common. I happens particularly in hot, humid weather ( like Brasil), since the water droplets have more inertia than the air molecules and so coalesce in the very turbulent break away air at the ends of wings and , particularly , any side plates. That because they generate the greatest local pressure gradient.
A big jet pitching nose-up at take off or on finals does the same thing in hot, humid conditions like Singapore or Hong Kong.
Way back there were some wonderful pics of the Brabham BMW's churning huge black vortices as the heavily rich mixture from the "rocket fuel" poured from the turbo exhausts up into a zone of turbulence caused by the huge angles of wing attack used to convert 1200 bhp of turbo qualifying power into downforce - very dramatic sometimes.

Both these vortices are coming off the front wing!
As FW's use ever more powerful techniques to manage airflow (and not create downforce) we are seeing these effects more and more. This year we've already seen similar vortices trailing off the cascade winglets above the wing to flow over the top of the front tyre (Ferrari) and also vortices forming under the front wing (caterham IIRC).
to get a feel for where these flows are forming and where they head look at this Sauber CFD video (pause at 34s to see the straight ahead flow conditions) http://youtu.be/pREgFVRXeDI?t=34s

Cool stuff. When was this first observed with the exception of the rear wing endplates?
Does it spin in a manner that would benefit to "seal" of the undertray? away from the car on the lower part.

Just couldn't stay away, then, Tony?

IIRC the Ferrari Fw cascade vortex was seen early in this season (may be around China?).
It isn't about sealing the sides of the floor, the vortex acts like a virtual turning vane directing flow to the leading edge of the floor, while simultaneously keeping the front tyre wake away from the car. Explained in AUTOSPORT+ here http://plus.autospor...trail-revealed/

Both images from @F1 technical forum
Here’s the Ferrari Canadian vortex image, not the obvious ones from the rear wing, but the subtle ones over the top centre of the front tyres
