Alexander Haydon O’Brien wrote about it:

“This puzzle was inspired by the cubic patterns on tortoise shells, and it is intermediate in difficulty. My thinking while designing was that the goal should be the removal of the shell / frame, and the fit and finish makes these movements extremely satisfying.”
