Notes on the level settings

The shapes that are utilized have different structures. I found that people have different reactions to these structural constructs.
If you approach it from a "Sacred Geometry" viewpoint you would use the shape most fit for the given nature of the task.
Examples:
Circular logic would apply to a cause and effect situation as in "increase sales volume" or "accelerate ability to project". This would work well with the Spheric shape influence.

The Hexagon can be seen as a "constructive" structure, if you are attempting to set off a domino effect that culminates with the manifestation of your goal the Hexagonal structure has an ordered and progressive influence on the overall trend.
Examples:
You want a promotion and there are a number of steps that qualify you.

Your uncle who is coming to visit always talks about politics and you want him to realize that his political issues are less than welcome. You want him to consider the feelings of others and forego his politics, this way he can spend the whole night telling you army stories.

A hexagonal structure would work well with the above.

The Tetrahedron!!!!
If you want Psychic shields and Remote Viewing or you want to take paranormal photography you want the Tetrahedron shape. OOBE, and any other more esoteric type of trend.
