This is much of a prototype for a model horadric cube from Diablo II. The biggest problem with it is that the underlying box isn't actually cube. I used a parametric box generator but it has made one axis slightly too long. I still like the look of it though so full steam ahead with a cube shaped version.
Further investigation leads me to believe this is actually a bit more like the nephalem cube, which is going to appear in Diablo III
