I can't seem to move around or look at anything else in the cell. I'd be interested what other commands / interactions have been discovered. I'll update this post if I find anything else interesting or useful.
This is definitely not useful, but this works: LOOK AT SELF. DROP PANTS. 
you can also dress the skeleton with all your clothes (pants, shirt, shoes and jacket).
Probably it's useless but the scene where you are naked and the skeleton is overdressed gives a good idea of the madness that is growing in that damn iron chamber
