Good lord, look at this Elite Portable Floor-Rising Screen that’s motorized. Carry it around with you, make it rise with its magic motors, and impress all those superficial suits on your next presentation road trip. Or, keep it right at home, take off that easily-removed handle, and it looks like it’s a permanent installation. Available by June, your choice of either an 84″ or a 100″ diagonal screen will set you back $2000. Screen sizes up to 150″ are planned.

It’s a nice start to a presentation when you press the button on the remote to raise the screen. Carrying it is not much fun though. It weighs about 40 pounds, which is OK for short stretches, but anything more than a short walk becomes a pain.
I’d rather have it as a permanent set up in a meeting room or home cinema. When we built ours, we made a high gloss cabinet around it. This makes for a stylish integration of home cinema in a living room.
But, you can also just buy the screen and make your own piece of furniture. You’ll impress anyone who sees it.
