Flying nut

Or screw, or some kind of another loose part that separated from ship and its now flying around inside cabin.

It woudl bounce from walls and kerbonauts and it woudl be affected by G forces, so when we accelerate, it woudl hit rear part of hull.

How about a golfball?

Or post stamps

Well post stamps woudl be easily sucked in by ventilation system.

I just got another idea, hanging plushie like that one russian use. For easy measurment of G forces acting on ship

So fun! Objects in the cabin reacting to G's would be great. Might require too much time and code from the dev's to make it worth adding (when compared to bigger features that take just as much). If they're going to be expanding the features of IVAs, however, that's one of the things I'd like to see!
