Ice Cubes (with .blend)

I was recently approached by my fellow Blenderhead and online friend, Kewl, asking about an ice shader similar to the one seen in the post 'Cuboid Aliens' by onetwothreesquare (http://onetwothreesquare.blogspot.com/2011/05/cuboid-aliens.html) and the original concept came from Emanuele Tenderini (http://emanueletenderini.blogspot.com/2011/01/dei-2.html). I thought I'd give it a try. So I did a very very quick doodle in Blender to see what I can come up with. And here it is:

I hope you like it. Textures are from Flickr.

In case you're looking for the .blend file (which has the shader setup and some compositing stuff), you can grab it on this link > http://www.pasteall.org/blend/6353
