A company called Data Vision has developed a new 15-inch LCD touchscreen called ‘Thru-Glass’ for retail stores that works through windows. The touch part works through windows, I mean, not just the light; that wouldn’t be that impressive. Beyond that, it’s pretty much just a regular screen, but it could be an interesting way to show off some of your products and answer simple questions even after the lights have been dimmed for the evening. For the £2,000 purchase price Data Vision will even install it for you, which is nice of them.
