a simple modern wordmark for your consideration =) the colours and rounded typeface give it the 'fun' element without being too childish, the U in 'juice' acts as the box for the games (drops) that are jumping out of it =)
I definitely like the simplicity. I also like how you made it a little less serious with the font - but the gradient adds back in a little bit of maturity. I prefer #14 over #13 - I think because I like how it plays off the color in "box." What I really like about this design is that it would work so well on cards and letterhead and just about any other item. Having said that, my partners and I still tend to migrate to designs with an isolated graphic element in addition to the text. I'm not sure about the drops - I understand the concept - but I still get a floral or tropical feel more than anything else.
