I have a few questions about the engine which would really impact whether or not I would plan to use this engine for a project I have.

1) Can 2D objects be drawn over the engine? (Similar to the framerate in the FPS demo) for the purposes of an interface...
2) Can the mouse interact with the Object3Ds? (clicking and so on)  i'm sorta  a  n00b in using the mouse in JAVA so  feel free to leave any ideas...
