Vidi, I love your variation on the "Q"...it looks very much like a technology logo. I wonder how we can tighten up the "health" part, though and make it feel more integrated with the "Q"? I don't care for the word inside the "Q", and the other one looks a little disjointed. Just a thought. If you care to play with that a little then I think you're on the right track. Thanks. I'm going to rank you high.
I like the font and the "swoosh" in #29. Can you do one combining the two with a swoosh that really ties the two elements together better (the Q and the "health")? Maybe with the swoosh in the same yellow as the little dash in the Q
Another idea I had...you know how the IBM logo has the letters with lines across them? How would that style look?
