I'm liking this icon, it could have some meaning! ;)
I do like.
I like the lighter blue a bit better
I'm gonna shoot some randomness @ you, just rambling
Can we try something like a 3 line E in the middle in place of the square? maybe too busy
Can we try with the slogan?
Can we try with the Entech.net
Also, can you shoot out some some other random ideas? I like your thinking and still have an open mind to ideas
