For Brickworld 2009, we want to build on the collaborative display that was started last year, the LEGO Mansion. This year, let us try to build on the theme of lighting (in keeping with the World of Lights collaboration). An AC power drop will be provided if you wish to use a 9V transformer. Also, a battery box may be used. Either design the power supply into your room or try to provide sufficient wiring to reach the external power supply.
Please make sure to mark the Mansion collaboration on your Brickwrold registration if you plan to contribute.
More details on the mansion collaboration can be found on the Brickworld web site. Any questions should be entered at the contact us form on the Brickworld web site.
