In the Video Encyclopedia of Physics Demonstrations, they have the
inertia ball on disc 2 demo 13. There may be other video clips but I would
have to check around. There are a wealth of related demos in the DCS,
section 1F20 - Inertia of Rest. Two that seem to be very similar to
inertia ball are inertia stick and inertia block...
