We've got a system set up now so we can store the chunks in a hash table. This, along with a lot of other modifications, allows us to add chunks easily while maintaining a quick look up of the chunk from it's position information. Also we've added the ability to raycast "into" the rooms so it's easier to edit

We've spent the first bit of time sketching out and trying our hand at making some custom textures of our own. I can't say all of them are great or look good together but it was surprisingly fun and successful.
