There seem to be 2 general kinds of submissions: One tries to visualize a gathering, the people side of the ideen-salon. The other tries to visualize the idea aspect of the event. We´re not settled on one or the other. But that much can be said:

-When visualizing a group of people it should not look like a "happening", and not like a regular "conference". Gatherings aim at intellectual exchange and discussion. However, although there is no formal hierarchy among the participants in a gathering, the situation is not symmetric. There is one idea owner and many people in the audience listening to him and later providing feedback.

-Focussing on just the visualization of "idea" is ok. But why not try to bring the people and the idea together? pegatinas has tried that already, but maybe there are other ways of doing it.
