Basically the idea is to add a dimension that generates terrain with a certain theme that fits minecraft but uses a different seed to generate terrain every time a player leaves it. ie. you'll never see the same terrain twice. Further, this terrain will have numerous new and interesting structures to explore and raid. It's possible that several themed dimensions may eventually be added. eg. a water world, a "sky dimension" etc. whatever fits in.
The next update will include a new dimension added by justenoughdimensions that resets and uses a new seed to generate terrain every time the player re-enters it.
