This is a design in an old Geneva square by Swiss firm 2B architects. I love the light an pattern created in the spacing of the glass blocks. "Using traditional sandstone, as well as glass blocks or cobblestones in a random pattern, the architects are letting you in on a secret - a lake used to occupy this land. The closer you get to the location of the medieval lake, the closer the glass blocks are spaced." (borrowed) This is a beautiful and subtle visual indication of a historical condition.
