I don't think they are the same person but Digi Design is a team of designers. And in regards to the contest I will give my vote to Kevin13 although it seems his logo is somehow distorted in a little bit in the middle where the hook intersects. I think it just needs some little improvement but the design is good as well as the others but in my perception Kevin13 design stands out. And one more thing just only two judges has decide and they are three hope we can hear a word or vote of the other one BitcoinBus by now, to announce the winners.
