Really cool, but can we get a "flat" version. Like something that would feel at home in iOS. Also, can you make a version without the coin, but just the 8 lines representing NEM? Actually, I was sketching logos last night and came up with the same idea as you, representing NEM with the 8 lines. I think it is the way to go for a logo.
I hope we're not ciritzizing you too much - Just wan't to get it right

Shouldn't the top and bottom of the letters be aligned ? I don't know if it would still fit into the coin if the "spread" is kept equal for all letters but the "E" currently looks a bit unaligned (I guess you wanted to keep the space between the lines equal).
