We are choosing (in alphabetical order) biggenius, ekobudis, logoz, rafa17 and sculptor for additional feedback and work. You are each in because of the strength of your design talents, as well as your responsiveness. None of the designs is a clear favorite. All have features we like. Overall, we probably prefer the blue and purple matched with silver or gray over gold. As we have progressed, we really like the 3d effects as they have become more pronounced. While we would like to avoid the overused "swoosh," clearly the concept of acceleration as depicted by arrows or similar renderings of "speed" are appropriate.
Acceleration must be as important as corporate. See #36, #117 and #52 for good examples.
I am seeing logos with my eyes closed, and will take a couple of hours before returning. Thanks to all!
