Whatcha buildin in Minecraft?

I'm constructing my vision of the Candlestone Caverns leading down into...THE MIDNIGHT MOUNTAINS.

It's a job, but I'm slowly making progress on two mile high mountains...

My Minecrafting is almost exclusively on hardcore flatlands. The building I do is to connect houses above or below the street level so I don't get punked by slimes.
