Deeper Madness

A deeper cut version of More Madness (which itself is a deeper cut cousin of Meteor Madness). A jumbling-only puzzle.

In Oskar Van Deventer's series of jumbling puzzles based on the geometry of the Triangular Dipyramid (see More Madness, Meteor Madness), this puzzle is not only the deepest-cut puzzle in the series at the time of its creation, but is actually considered to be deeper-than-deep-cut or have a deeper-than-origin mechanism.

There is controversy over exactly how to define a deeper-than-origin puzzle but Oskar defines it from a mechanical perspective. If a puzzle's cut curve boundaries span exactly 180 around the origin of the puzzle, it is "origin-cut" or "deep-cut." If the boundaries are either smaller or larger than 180, the puzzle is "shallow-cut" or "deeper-than-origin", respectively. Take a look at the 5th museum picture to see the >180 cut curve.

On this puzzle in particular, the deeper-than-origin mechanism is proven by the fact that, when certain jumbled configurations are reached, "a cut seems to be running all the way through, and you think you can turn it, but actually you can't, because in the middle the mechanism is blocking [it]," (see Oskar's Deeper Madness video on YouTube).
