#3 - has potential...like the symbolism of the measurements and the idea being conveyed. probably more of an iconic style with the text being less prominent. we dont want to confuse people that it is a logo - simply a applet on our website. It will be an important applet though and thus deserves it's own icon.
In general - all designers should see our applet at below link.
i am still prefering more of a simplified message to just represent the icon SOFA BUILDER on our site. This is sort of more complicated than necessary to launch this application. I am preferring something like the simple "S" that was entered in the contest. Simple, clean, modern, iconic....different and not competing with our logo itself.
