#47 has a lot of potential. I do prefer the Silicon Valley Link to be horizontal.
Several ideas this gives me:
Can you show the cool picture more as a compass, where the north, south, east, west points are slights larger that the others? I think this would be cool!
Can you try the written part of the logo not just horizontal, but in a multi color, and also single color but also horizontal, bolder and a deeper saturation, like the purple or red on the picture (they seem much more saturated)
#63 I think is too stylized, too much a fancy compass, but I see now on the others, making the N, S, E and W points bigger may not be so good. Can you think of something that accentuates those points but does not look so out of balance? I think it might be that the bigger points make the inner circle look too big, do you see that? Also, maybe a less fancy compass, on its own and/OR incorporated into the other design?
