trying out some new ideas:

Something is not right.
Possibly it needs to look more 3D'ish, looks like a flat 2D image or maybe it needs a small black border
I was totally psyched about that logo until UP pointed out that they look a little like helmets (which is undeniable).
It's ruined now

Remember....if you look at anything long enough it starts to look a bit crazy....although I do like it I must admit
that those who see a C instead of an E do have a point so maybe this is not good enough. But the originator
of this logo does deserve plaudits.........almost there mate.......so close..!!!
