Dear designers, what we want: creative, elegant, conceptual design. One of the applications will be a sign hold by our drivers in crowded airports and this logo has to stand up. In the other hand, what we do not want: "ST" logos, image of planes, cars, drivers, wheels, roads, etc (remember, we want conceptual stuff!). Thanks for all who are submitting your ideas, some of them are very close! Kind regards, Hugo
