Some possible pieces/features I think would be in the collection:
• A Matryoshka doll style piece where each layer is a xenonite reconstruction of the carapace of each crew member from biggest to smallest with Rocky in the middle. In each one the eridian is clearly dead and has the cracks and blood from when they lost the radiation fight (Also eridians can tell from body language or position). Rocky is the only one alive and looks terrified.
• A smaller room/section of the ship where the internal communication systems were centered that Rocky tore apart and reshaped because he obviously didn't need it anymore. He recreated the crews bodies in life size pieces and wove the strings through them, connecting severed legs, bits of carapace, and organs around the entire room to create a 3D horror show. The mission tattoos and marriage marks of his crew members connected to crate an eridian phrase that means a hopeless task where the participant has essentially already died before beginning.
• A vast, busy looking mural of space that goes from Erid all the way to Tau Ceti with a bunch of features such as asteroid belts and energy signals. So much that its honestly hard to pick anything out unless you listen very very carefully and hone in on it. Mixed in there disguised in all the calculations and such are depictions of eridian predators that essentially jump scare whoever is examining the piece. It creates an incredibly primal panic feeling just by being around it even before spotting the predators because the viewer's brain still detects them unconsciously.
• A space in Rocky's workshop which is a closed box and when inside no noise can get in and you can only detect yourself. The sounds are amplified and reverberate back to such a degree that it's overwhelming. Crudely scratched on the outside is the phrase "To Watch Myself". This is clearly where Rocky had been sleeping.
• A collection of slates scattered next to the large machine that stores information for the crew. On them are notes about every role on the ship and how to do them. The notes start neat every time but deteriorate into slapdash large scrawlings that are deeply carved into the slate and seem to have been done in a fury. At the bottom of each one are dents and chips where it had clearly been struck repeatedly, with mercury staining each. On all the slates there is a sheen of glue that had been added later with crumbled carapace and bits of claws/hands stuck on that match Rocky's. If you look closely at Rocky it becomes obvious that most of his claws have been regrown several times.
• A 3D scene with Adrian laying in their nest, which had been changed to accommodate a clutch of eggs. They have their legs protectively surrounding said clutch. Adrian is slumped backwards limp against the wall with cracks and crumbling carapace all over them, a pool of mercury staining the nest and eggs. Inside the eggs the babies have similar injuries. It's identical to the injuries and side effects the crew had suffered before dying. Later on Erid it is speculated that this was Rocky's fear of returning home, as he didn't know if an unknown disease was responsible for the crew's deaths. One of the most disturbing aspects of the scene is that the mercury pool is real eridian blood, presumably added by Rocky himself over several months.
• Another scene featuring Adrian where they are surrounded by the families of the crew. Adrian is standing over a mess of mashed flesh with bits of viscera and mercury (real) staining their claws and arms. Each family has a piece of leg or carapace what was clearly torn from Rocky. Surrounding the mess in the middle that's clearly all that's left of Rocky is the phrase "Not Enough"
• In the common area are the hellraiser sleeping rigs for all of the crew members with incredibly detailed realistically recreated bodies on each of them. The level of detail for all of them is so precise that even the organs/anatomical variations are accurate. The recovery crew legitimately thought these were the actual bodies for a few minutes before they went in and inspected further. Each is respectfully fitted with a small pipe in one of their breathing orifices that connects to a central air pump. When it is turned on each body makes one gentle but incredibly lifelike note that all mesh to create the word "Together". The uncomfortable implication of this piece is that Rocky spent several years doing invasive echolocation on each dead body so that he could make these.
Feel free to reblog with your own ideas! I'm a sucker for angst.
