Like entry #9 the best. Though I think the people who will be viewing this on my biz cards and websites might not be able to recognize that the first letter is a "J". Really like the design concept of it though, very cool & creative, I hate to say it but if you could maybe dumb it down for us a bit we would like to see more.
Don't care for the design or color choices of #1 though. Too simple, too blockish, colors are not pleasent. Love that you chose to use colors, but those ones just remind me of the bad 1970's decor we had in my house growing up.
