L/W = 2.000 T/W = 1.384 T/L = 0.692 P/W = 0.564
C/W = 0.119 H/W = (P+C)/W+0.02 = 0.703 P/H = 0.802 C/H = 0.169 Vol./W^3 = 0.751
Addition # 11 - Cut this in refractive indexes 1.54 to 2.14 with no changes. This is simple to cut and will work well in about any material and is designed for shiller/color. Also it works well if you split color over the center so that the color rocks.
