UML CloudLogo Design Contest

Here are some hints
- UML (Unified Modeling Language) is visual notation to represent software system logics and structures. (http://www.uml.org)
- You can get some hints from our previous (about 10 yrs ago) product, StarUML ( http://staruml.sourceforge.net/en/ )
- UML Cloud is web-based tools like as Google Docs, Lucidchart, Trello, Cacoo, etc.

One more hint
- We are planning to use "Flat UI" style for our web application like as "Google+"

(IMPORTANT!) The logo could be placed in both black background and white background.
Please check the attached image file which is a screenshot of our product. The logo could be placed in top left of the screenshot.

Hello! Here are some hints for getting the most out of your contest as it progresses:

~~ You, the Client, are very important! Your active participation is the single greatest factor influencing this contest. Active participation by you, the Client, helps you get the logo design you want!
~~ What's active participation? It's updating the brief with more information for Designers to work with as the contest progresses, providing feedback to Designers on their entries when they're submitted, and ranking designs at least once a day.
~~ When you provide feedback to Designers, you increase the chances of getting the logo you want. More feedback = better results!
~~ Leave private feedback by clicking on a design. Feedback will be made public upon contest completion.
~~ Rank designs at least once each day -- this will encourage Designers to submit more entries!
~~ Ranking prevents your contest from going idle! Active contests attract more Designers.
~~ Ranking gets your contest noticed. Unless your contest is Private, 1st place entries are posted to the portfolio page: https://logotournament.com/portfolio
~~ Please note: if you're asking for a design that will require several hours to create, to attract Designers willing to invest that amount of time the prize should be at least $400-$500. All "Character" style logos fall into this category.
~~ Designers are not offended by "Not Interested." We'd like to know what you don't want so we can give you the design you do want.
~~ The first phase of the contest is the "Open" phase, and everyone can submit during that time.
~~ After your contest's initial "Open" phase closes, it will enter the "Top 5" phase; only the top 5 ranked Designers will be able to submit revisions at that time.
~~ The "Top 5" Designers are the first 5 Designers in a contest, not the first 5 designs.
~~ When "Top 5" ends, the "Judging" phase begins. The Designer of the 1st place design will be the only Designer who can submit revisions at that time.

So far, very cool and beautiful logos! Thanks to all designers participated in our content!
Actually, it is so difficult to represent "UML (Unified Modeling Language)" as a logo, because it's a very abstract concept. UML is the key of my business.

To give you some more hints. UML diagrams is considered as interconnected boxes, ellipses, etc with lines and arrows. To see actual UML diagram, please visit here ( http://creately.com/blog/diagrams/uml-diagram-types-examples/ ).

I'd like to see more enhanced logos reflecting "UML" concepts very well.
Cheers!
