Mettle has recently revamped their website to something much more functional, and there seems to be regular updates, so check back often.

Here, Nancy from Mettle sets the stage for a ShapeShifter AE tutorial from Tim Harris who has created a Crystalized Animated 3D Logo right in After Effects using ShapeShifter AE.

from the tutorial description: Nancy presents a tutorial prepared by Tim Harris. He created a logo animation for his company using ShapeShifter AE, in After Effects. The crystal finish is very cool. Tim was kind enough to prepare a tutorial to let us know how he did it. Thanks Tim! Great work.
