This is inspiring:
I'm thinking, Why make it a stationary display attached to a house? Why not make something like this portable, made up of a set of individual components, all linked by WiFi or some such technology? I envision a beautiful display like this made by a group of nerds (we know who we are) and set up at, say, Kapioloani Park, for evening performances. Maybe just for Christmas, maybe for other times of the year with various kinds of music. Kind of a flash-mob approach. Set it up, do the show, take it down, all in one (each) evening.
