Ok this tutorials will show you how to get a really cool glass-crystal effect.
Start off by resetting max. Then choose the geosphere object and draw a geosphere on your perspective view

now to the right, under the geosphere settings unclick the smooth option, and choose Tera for your shape.

This should give you a nice choppy image like the one below

Now we are going to extrude each patch of the shape. To do this right click on the image and choose convert> convert to editable patch.

Then right click on the image again, This time it should have a lot more options, click on "extrude Patch"

Now click somewhere on the image. When you put your cursor over the spot that you clicked a new cursor image will appear. When it does, hold down the left mouse button and drag. This should start to pull a piece of the shape outward
