    Attached is an idea ;-) It don't look too bad when resized as a 16x16
icon.

This could make an attractive _logo_, but it would _not_ work as a 16x16
icon, IMO (see attached). Clever combination of E with gnu head - bravo!
But, as Richard pointed out, that makes it hard to distinguish the E.

Let's not forget the story of "The Gnu Who Became a Mushroom" - that's an
invaluable icon lesson. If shrinking a gnu head can turn it into a mushroom,
there is no hope for shrinking E-gnus and other such artistic subtleties. In
particular, shrunken heads seldom appear brilliant.

16x16 is a hard nut to crack.
