I think I might have just gone overboard on this one... I find myself physically unable to add more triangles to this design. Looks absolutely stunning in any material with an RI of 1.52 or higher, and does some really strange things with dispersion and RIs above 2.00. THE ULTIMATE TRIANGLE CHECKERBOARD! Suggested size = 20-50 mm. Yes, that big.
