This is an animation of a rotating hollow mask. At the moment you see the back, so that the hollow side is pointing to you, something surprising happens. It doesn't look hollow, it looks like a normal mask - rotating the other way ! The most probable reason is that our vision doesn't accept hollow faces.

There is always a hollow side. Oh I found it neat if I was looking at it with just my peripheral vision it would reverse direction until I focused my vision back on it at which point it would go back to counter clock wise.
Yeah, same as the other two comments. It looks exactly like a hollow mask.. Peripheral vision it rotates opposite direction..
Yeah I only see it with my peripheral vision. It always dissappears when I look at it.
