Please take a look at this photo. I'm trying to make a crystal text similar to this. I tried it in 2D but it didn't work out as good so I wanted. I tried having blue infinite lights of different shades shine on a crystal texture beveled text however that did not turn out anywhere near as similar to this (I only focused on the lights coming from the left).
Here is my PSD file, you don't need any other files since it's material straight from photoshop. http://www.mediafire.com/download/26vwfgz28u5qqqp/Glass_DK.psd
