In this tutorial I’ll walk you through my first attempt to render a Quartz in Mantra in H16.

If you’re brave and have Java installed and activated in your browser, this applet by the (german) museum of Crystals and Mathmatics (ain’t that great?!) gives a pretty good idea of how crystal shapes originate.
