Glass Cubes Texture
Create a new document (i made it 300*300px), black foreground, white background.
Apply the Clouds Filter (Filter --> Render --> Clouds).
Now apply Filter --> Render --> Difference Clouds two or three times.
Goto Filter --> Distort --> Glassr..
Set Distortion to about 14, Smoothness to 3, Texture to Blocks and Scaling to whatever you like, I used 50%
Yo, this looks like glass..
Last step is to Hit CTRL-U and pick a blue (or another color) for the Glass Texture.
I used 207/15/0
It should look like this now:
