This is verification of the La Quinta Columna research from a while back.

There was another verification of the La Quinta findings, but I cant locate it presently.
I agree with you that this is confirmation for La Quinta Columna.
The other video you might have watched (I did) is in German, and it shows moving and self-assembling particles under a microscope. It was independent of La Quinta. Scroll down to video. The video runs a bit long (boring to me) but iirc at the end it is amazing.
