Bro, it wasn't originally there, but since you're asking, I added the newest option from the latest 3D data library update, which allows the use of textures. I also added an opacity control; although it won't be a perfect crystal, you can get a pretty cool result by combining textures and opacity in the current version. Besides downloading the js file, also download the demo to copy the dice-box folder with the new themes included. In addition, I added wood, two steel options, stone, and polished the default. Hope you enjoy it!
