A jumbling-only puzzle based on the triangular dipyramid geometry.
Edge of Insanity is a shallow-cut edge-turning puzzle, but with the slice planes aligned with the faces, and not the edges. It is probably the simplest of the possible slice patterns for this geometry, but the puzzle is far from simple to solve. All the pieces except the core are visible on the surface of the puzzle.
The puzzle was inspired by Oskar's "Madness" series of puzzles, and the debate surrounding the meaning of "deeper-than-origin".
