what it would look like inside a mirrored cylinder (that slowly shrinks)

This is a repost of my "Short" version of the same video, but in Wide screen.
it's a heavily raytraced(max raydepth) video inside a perfect mirrored cylinder that slowly shrinks, the ceiling is also mirrored but the floor is not.
yes, I'm working on more "what if" space like videos, but I'll probably also post more mirror like videos, cause I think they are interesting. also i wanted an HD version of this posted.
this video is very Visually Noisy, and Youtube encoding does not like visually noisy videos, going forward I will take steps to make my videos less noisy visually. I spent waaaaay to much time trying to clean up the video, and I would rather just move to a new project now
