Moving Props

I've seen two shows so far that have had moving props.
micromarching.com/show/3bd8/not-another-guard-show...
micromarching.com/show/3bcn/a-light-in-the-dark
I've tried to move the props but they don't do anything.
I know it's not a bug, I just want to know if anyone knows how to do it.

It is a new feature that Joe just put in. He has only allowed a select number of people to try it out, to make sure it is bug free before releasing it to the rest of the site. As long as there are no problems with it, I would imagine he’ll release it to the rest of the site sometime this week (don’t count my word though).

Oh Ok. Thank you for explaining that.

I thought I saw another show with props today that moved. When will this be feature be available for all members?

When Joe releases it for Premium subscribers.
