First off, after some story idea discusions for movies and such my friend and I stumbled on this site and found it very interesting. This is sort of on and off topic, but here we go.
We've had this idea about building a room that would be sphereical, ideally you'd build it in space to make it as perfect as humanly possible and for weightlessness to get in the middle of it.
So you have a sphereical room only it's a giant sphereical mirror that your in the middle of now what on earth would that look like? Put questionable physics aside on how to get in the middle and much less on how to light the thing and please give me your thoughts on what it would look like, I kinda see it a s glimpse of what a 4d (if they existed) creature would see of themself.
