I like how they've used arrows in the attached logo and image within the article to symbolize choice and movement. Your entry #4 shows this as well with the two doors buy I think it would be hard to keep clean and consistent with different media (print, tshirts, etc)
thanks for all your input, I just think something that is simple and corresponds to the name of logo. to put in various media, logo colors have several derivatives that can be used. just as the use on the website, the logo could use a color that has an effect, or on a t-shirt and other print media could use a solid color with no shimmer effect. The most important form of the logo does not change, even using only black and white.
