Your scene lacks a few crucial ingredients that make real-life glass 
cubes look like glass cubes rather than thin air:

* Reflections. Use a sky sphere for starters.

* A slightly absorbing material. Use the fade mechanism or media.

* Reflections. Use a less uniform ground texture.

* Shadow effects. Use photons to produce caustics.

* Reflections. Use specular highlighting to make the light source reflect.

* More reflections. Bevel the edges and corners so we can see the light 
source reflecting on them.

* Did I mention reflections already? :-P


Even then, real-life glass cubes /do/ tend to look weird. Curved shapes 
make much more believable glass objects, even in reality.
