Is there a way to make procedural materials like the ones here in Cycles for rocks, sand, landscapes, etc.?
Here's an image of what I'm trying to achieve:

I would say yes.
Here is an example I made in a few minutes entirely with material nodes:

Note that the color ramp near the bottom of the screenshot is going from 0 to 3 (to make the displacement stronger). To make colors darker or lighter than 1 or 0 you must type the values in directly.
Also note that the above image is rendered with Cycles experimental displacement.
To enable this you must enable experimental features in Properties > Render settings > Render > Feature Set:

This enables the Displacement settings in Properties > Object Data.
Veronoi Crac node setup (and possibly the ColorRamps values and colors - tried to figure out a nice setup myself)... for the rest, the setup is working very nice for a Sea Shell I'm making. Thank you!
