The name of the project as "SoakUp" is already decided, and a very early (German-language) prototype of the application is running at http://www.soakup.ch/. The idea behind that name, formulated as a (somewhat exaggerated) claim: SoakUp makes learning so easy, you will have the feeling that your brain just soaks up the learning matter, quickly and without great effort.
Right now, at the start of this contest, we have the opinion that some crude pictorial rendering of something really soaking up something else, say a sponge soaking up water or a brain soaking up words, will *not* result in a good logo. We think the way to go is more subtle. But one the one hand, we don't have an idea of that way yet, and on the other hand maybe some good designers will surprise us and prove us wrong.
We hope to be successful with SoakUp mostly among young people, pupils and students here in Switzerland. In our mind, the perfect logo would be "fresh" and "modern" to attract this young audience, but not too much so because we want people to see SoakUp as a serious tool and not mistake it as a toy or even a game.
