Hello. I tried to draw something close of your existing logo, because I am not sure if it is good to create a new logo very different by the old one. I guess your clients do not agree a very big transformation of your logo. I used 64 squares - meaning 64 bit. On the first time, I tried to use blue and navy blue but the color were confused with the color of the website, and then i used a dark red and a dark purple. The circle around the G is transparent turquoise or transparent yellow. I drew the cercle transparent, because i think more important is G, not the cercle.
