3D Room (moving)

Hello JGO,

Today I will show you what I have been working on for a little bit. It is a 3D room that is viewed in first-person. I built this room using only the libraries that came with Java 1.7, no external libraries such as LWJGL. Here is a screen shot of the room.

Any feedback or comments would be great.

Greetings,

P.S. Thanks to the Cherno (http://www.youtube.com/user/TheChernoProject) for help with this.
