Deeper Madness is a deeper-cut version of More Madness. It has a "deeper-than-deep-origin" mechanism, like Dave Pitcher's award-winning Rotoprism 2. Deeper Madness is a face-turning puzzle with six screws under the six turning faces. Starting from a screw, the associated visible cut at the surface is more than 90 degrees away.
Deeper Madness also answers Dave Pitcher's question whether a puzzle with a deeper-than-origin-cut mechanism can be solid. This puzzle shows that it can. Notice that there is still a controversy about what constitutes a deeper-than-origin-cut mechanism.
