Smart video projectors do away with screens

You know how you have all those walls in your apartment, but none of them are large enough, smooth enough, or white enough to use as a projector screen? Well there are these new smart projectors that use camera feedback and special projection techniques to automatically calibrate themselves to look good on any surface, no matter how rough. Sure, you're not going to get HDTV quality images (though the images do look fairly good) but you'll be able to project cute cartoons on pretty much anything, including those sinfully ugly curtains you keep meaning to replace, which is certainly a step forward. Just be careful watching your "home movies" on those street-facing windows.
