E-ink would actually be a pretty neat practical version of this kind of stuff. You get the relatively static display geared towards focus, without all the waste of printing out paper. I've felt like it's a really under-utilized technology. I know it's used in some displays for advertisements and information, but more research into it could bear a lot of fruit in low-energy-consuming electronics that don't use constant input. I'd love to see more software geared towards its use (and to be honest this thread is kind of inspiring me to go off and develop something) and more personal devices that use it. Especially when we're talking about environmentally conscious design, I don't think you're gonna get a more low-energy display than that. Hell, even the paper printing probably uses more energy.
