More Minecraft Programming

I haven't looked into reading picture data at all yet; instead I worked more on making cool structures programmatically.

First, I cleared out a large area.  This is a 256*256 area, which is equivalent to a quarter of a region, or 16*16 chunks.

Annnnnnd here's what went in there:

A giant glass hemisphere!  I also made a regular sphere:

The last thing I did was turn all of the water from one region into lava.

Here's a top view made with a mapping program called Tectonicus:

That's all for this week.  I plan to make the picture program and do more work on making cool minecraft things soon.  First though, I plan to finish a project I'm working on right now that's unrelated to minecraft.  Hopefully by next week it will be at a point where I can show it off.
