3D Cube in Photoshop

I really enjoyed seeing this cube come to life. I created it using a YouTube Photoshop tutorial by Gavin Hoey. I did a couple of things different. First, I used fixed size to create the square and then I used exact measurements rather than free transform to reshape it. Also, I only made two squares. For the second side square I simple duplicated the layer (Ctrl J) and flipped it horizontally.
This jpeg image doesn't show as well but once you create your own, you'll see how the light passes through.
Enjoy!
