- add Volume (and Blocks?) to the Copier class and expose to Iwb
- tutorial on creating signs
- add a consistent way to discover and delete signs, switches, monitors
- add ability to switch on/off deug logging from ipython
- make logger only debug mciwb - other loggers are too noisy
- towers and walls
- a drawbridge / portcullis that open and close
- a rotating object using blocks (with a face on)
- or even better a patrolling tower / robot ?
