Maybe something will pop up in the future, we can only hope.

I have never seen smoke in a wind tunnel actually expose a vortex.

The only time I've seen a vortex exposed was in the Aerodynamic Oddity thread video posted via NCAC 1941 with a wand and long feather like tuft strings twisting about a cube.

Sure I've seen still photos, and laser pulse images, and CFD images, just not rolling film footage of smoke in a wind tunnel.
