This icon is a cube that represents thinking outside the box, which I believe to be a quality of a great consulting firm. Its also a hexagon as well, depending on which way you look at it. A clean, clear, modern and easily recognisable logo. It will work well on any medium as there are no special effects or blends just solid colour. and will be clear even in greyscale.
#91) I like this a lot. However, as an ex-employee of Coopers & Lybrand (as are some of our clients), I think the vertical line to the left of the text is too reminiscent of their old logo. See: http://www.brandsoftheworld.com/history/2001/10/35827.html
Could you keep the cube, but remove the vertical line? Does that still look good?
Here it is with the line removed, the line isn't really part of the logo anyway it just a way us graphic designers like to separate icons and text. I'll be away for a few days tomorrow, so if I don't make any more changes you might ask for straight away you'll know why. cheers Julian
