Audiovisual and technical Congress Support in an unfinished building - it is always rewarding to face (and subdue) specific challenges of a special location: imagine light shielding of an auditorium still "under construction", providing optimal acoustics in a bare concrete room, building a screen and stage set into a "raw" hall... However, the effort was worthwhile and the result spectacular. Our ultra-wide screen set, "electronic" moderator desks and individual SMS- and Twitter-based audience interaction proved to contribute (again) to a great success story.
