Translucent, bright, and airy concrete? Yup, Hungarian architect Aron Losonczi is making the usually cold, drab material artsy.  His new technology embeds concrete with parallel strands of hair-sized optical glass fibers that span from one side of a slab to the other.  That allows light to shine through, making walls several feet thick look like fabric.  Shadows of trees or people outside can easily be seen from inside.  And since the fibers make up only about four percent of his concrete, Losonczi says it's plenty strong enough for building load-bearing structures.
