Anyone here have Minecraft?

I've recently been playing minecraft. It's a pretty cool game and I have a lot of fun with it. I mostly play Alpha and building mode multiplayer.

If you haven't played the game, here's an example of what a map can look like. I built on it, but i didn't alter the natural map too much aside from mining trees. The map generator can make some really awesome stuff and it's fun to just wander and see what you can find. The maps also get bigger as you explore past your current boundaries.
