>The Magic of transparent concrete.
>So I found this article the other day. Basically it amounts to concrete that is structural but at the same time lets light through. There weren't any picture with the original article but I found some in the link above. It's pretty awesome and kinda mind bending. It's like that indicator light on the front of your MacBook Pro that flashes to let you know you're in standby. The better thing about this concrete is that it isn't just a bunch of little holes like on your MacBook Pro.
