As far as the actual installation is concerned.  I have thought about cutting out circles and installing those on the walls to see what happens with that.  I have also thought about the possibility of stretching fabric around the circles that are on the wall.  I've also thought about constructing and putting together a large installation of forms that mimic the shapes of Necrotic tissues and mold to create this organic area where the projections will be cast.  Here are a couple images that I've looked at for installing somthing on the wall.
