On Minecraft Live Oct 3 we announced the Caves and Cliffs update, which includes (among many other things) new cave generation. Here is the extended version of the cavegen demo we showed there.

Here is the soundtrack:

- Youtube:    • Once Upon a Time in the Underground  

Now over to you. What kind of caves would YOU like to see in the Caves and Cliffs update? Inspire us! Post links, pics, videos, drawings.

Some disclaimers about this demo:
- The mountains at the beginning and end are only placeholders (the actual mountains will probably look quite different).
- We use glowing ores as a placeholder for possible new yet-to-be-added light sources (no promises though!)
- Some of the caves in this demo are really huge! Those will probably be rare. When prototyping we like to push the boundaries to explore what is possible. We'll also have small claustrophobic caves, plus some of the old cave generation.
