We are really liking this idea (# 79). Could you do a version with the "D" rotated counter clockwise a little more? We think perhaps the concept could still work with the D not being quite as severe and would like to see it that way. It's interesting as is, but would like to compare. Could you also do a version of that same "D" concept using a jet (as in your version #57) instead of the Wright Flyer? We like both, but need some others to weigh in with their opinions.
