Stenen die licht doorlaten...bouwmateriaal voor de toekomst?

What a human can think about he can invent. I found these movies about stones (concrete) which are able to let light So if we are able to build houses with these stones we will need less power and we will have more light in the houses. This future concrete can have lots of possiblities in our real wold. Just think about the apportunities to project personal messages on concrete with the use of displays?? Do you see possibilities for this innovation?
