hi thanks to rank my designs so high I tried to create a "simple" logo but that express what you do in your business... the box part is obvious :) ... all the icon is made with boxes that also makes the figure of one "open" box... the piece that is going out (or coming, it depends) is the meaning of "thinking out of the box"... also means one box that is "shipped" around.. making a visual metaphor...
please don't mind to ask about anything more you wanted to see... and remember that even that the contest is in judging mode you can switch the first place among the designers that you want and ask for changes or updates of their logos (just the first ranked can do it)
