#68: this has a lot of potential. Very creative! Few things that perhaps you can try out: 1. Can you try and use upper case letters? Also perhaps a less "geeky" font? :-) more streamlined perhaps. 2. The letters themselves, can you make them made out of squares as well? like #69. (you can keep them with white fill) 3. As for the background, the green looks too "techie". Perhaps try to play with different backgrounds? 4. Perhaps you can try also a version where the background squares have recessive color/s and the letters are made of squares of single dominant color? Would be interesting to see how it looks.
