/cgl/ - Cosplay & EGL

This might not be feasible, but I figured I'd ask anyway. I'm planning out a 9S cosplay, and while most of it is pretty straightforward I'm debating what I can do to have his Pod (the little square robot thing in the picture) floating over my shoulder as I walk around.

The easiest way to do this I can imagine is to have some kind of clear plastic arm or wire supporting a lightweight pod from below, but I'm worried that would like really terrible and tacky.

I've considered making the pod out of extremely lightweight materials (essentially just having it be a hollow kite made of paper) and then having it hang from a balloon on a long enough string that the balloon wouldn't be visible in most photos. But Thats going to be fragile and prone to accidents, as well as I'm not sure I can make the pod light enough for a simple balloon to hold it up.

Are there any other tried and true methods I should be considering here? Or am I being too ambitiuous?
