I've been playing Minecraft for a while now. It doesn't look like much at all, but it's a really fun game. I love the fact that you can build whatever you want. It's like legos, really. Anyway, I built a Stargate in Minecraft. I originally wanted to use the portal blocks, but if you stack two or more together, they just vanish. So I decided to make inner part of the Stargate out of glass and water. This means that you can't walk through it, but it still looks kinda neat. I figure that I could make a wall of water if I had a trough that ran through the middle. But this would mean that you would fall into the trough every time you stepped through the Stargate. There might be other ways... I'll see if I can figure it out. I used lightstone for the chevrons. The gate is bigger than it would be normally, but that was the only way I could make a circle that looked decent.
This is with the default texture-pack in Minecraft. It would probably look better with a better texture-pack.
I'll try to build a DHD next. Probably won't be able to make it look as nice as the original, though.
Here are some better pictures. I'm using the Minecraft Enhanced Texture Pack 256x256. I also noticed that I had placed one of the lightstones in the wrong place. I fixed that.
Here is the world file (it's a zip) if you want to check it out. It's from my multiplayer server and so there are a bunch of other creations on there, that my friends made.
