IDEA Xscape extended

Here is a set of sketches for another variation on Joern´s idea of an exhibition landscape ("Xscape"). The platform got a bit more volume, a level-step to sit on, and a variety of showboxes, large and small. We may think about whether placing this "stepped" and "morphed" landscape on the hill-slope too. Another addition might be to include one or another of the existing trees into the platform.
