Since its a projector system, I bet what you see is not the heavy part, the mirrors mounted in the attic is another story and well, if people can walk in the attic, then this can sit up there(weight wise). The hardest part is cutting a spot tall(looks too wide to fit between standard trusses) enough for the screen, but even that is not too hard to be honest.
I actually find this offensive. have we not learned the social and psychological damage of this kind of conspicuous consumerism? you know that kid is going to be a spoiled prick. what redeeming quality does this provide? its embarrassing and pathetic and i hope it falls on the kid while he is engaging in "relations" with his mother
