I'm not liking the pixelated font used in #131 and #130.
So far #126 is your strongest idea. But I'd like to see a version that shows the symbol on the left next to the words. I'd like to see what you can come up with for your interpretation of the cube. Remember, I don't need it to have a 3D feel... I'd prefer that it be flat and very clean and sharp, but still have the essence of the original. Stay away from gradients, shadows, reflections, transparencies and things like that. Sharp and minimal.
Good luck!
