I think all these ideas are great! Creating sounds for an unfamiliar or imaginary environment would be awesome. The microbial environment could be very interesting...We'd have lots of room for fluid/liquid sounds, and we wouldn't need to do much visual stuff, if anything. I've pulled a bunch of reference images to model the inner ear (it should be a pretty easy job), so if people have ideas for what we might want to do with the model, just post!
Looking forward to fleshing out a bit of a storyline, see you guys soon!
