Muniac Manor - Indoor Training

I was wondering if anyone has riden their unicycle on a standard treadmill.
Given the friction between the uni’s tire and the tread belt is seems possible.
I’ve never tried it though. I’d like to put together a setup to be used indoors
during very cold weather. Small obsticles could be fastened to the belt to make
the ride interesting. Using velcro so they could be moved around. The front/back
of the treadmill could be elevated to simulate up/down grades of small degree.
Just curious to get some feedback. Don’t hold anything back.
