Thanks for your three entries. Unfortunately the red cube logo on a black background is not practical for me while printing and the logo on white means you cannot see the white blocs coming out of the cube! Also the cube needs to be build up out of serveral blocks like the Rubic Cube. The colours of the black, silver, orange logo I like including the font, but the cube is open instead of solid with smaller blocks. May be you can work on this concept to make it fit.
