Farsight "opening portals" in Atlanta got casually dropped awhile back in one of the videos. They didn't follow up with a How To or anything though.

What's your preferred method for making compact energy vortexes?

I get some selenite sticks about 8-9 inches long, a bit thick, make a 6 sided small octagon and stack the selenite up. I then put some of strong stone in the center, like a satyaloka azeztulite or herkimer diamonds.
