Want to lord it over your friends next time you hold a garden party? How about setting up a 40×60-foot cinema screen in your back garden? Bayraider has found one on eBay going for $10,000. Obviously, you’ll need a pretty powerful projector to make the most of it. And some way of getting the thing from its current home in St Louis. But still, it’ll put your mate’s 60-inch plasma in the shade.
