Tutorial: Star Trek TNG warp stars

I always struggled to figure out how the VFX team on Star Trek: The Next Generation created the warp stars effect for the series.  It was in 1987, and CG was still in its infancy.  When I was researching for my VFX History video on the show, I discovered that this effect was actually created by John Knoll using slit scan.  And so, for my other VFX History video on that technique, I figured out how to recreate the look of the warp stars using CC Particle World, precomps  and the Echo effect.
