umm... build your room so it isn't as big as the world? :) no, really, use a cube for the floor and make it finite, there bud. :) oh, are the bricks on a diagonal because you're using the default camera location? i saved a default file where i have the camera set square to the world, not on an angle, so i'm not used to things being skewed. (makes it MUCH easier to rotate things in view!)
