A few NEM logo sketches, on behalf of my friend who does not have an account here.
I prefer the first logo on the left of the version 1. Actually, since we are aiming at being the silver NXT, I'm guessing that the siver one shoud be more appropriate, but I found the gold one to have more punch.
The two on left side of the version 8 are also very good.
Anyway congrats your friend, he did a very good job!
