Both your entries so far are great. I like the typeset contrast of entry #11 but would like to see an icon/image element in it. Awesome so far though, really like it.
Hi there, there is a problem with the usa style plug i used in my design, as Dragonfly, a fellow designer, has already used that concept he is now asking me to withdraw, so i will try some alternatives and will hopefully upload again soon :)
I think it's fair game though. I'm even a little upset that Dragonfly called you out on the plug, as that's a pretty common association with energy consumption. I think the design would be amazing if we removed the arrowhead and turned the 'O' into an on/off power symbol that was stylized like the 'hop' typeface.
..actually, as i was just about to send the designer a question, ive noticed more than one designer using the letter O as a power button, so i will upload for you shortly :)
