3D face optical illusion: Rolling eyes on hollow mask

is it bad if i saw it concaved right away?

trippy as fuck when your tripping . . .. . . ha

OH MY GOD ILLUSION MUCH!

thats really interesting. Majority of people do see it in that way. It has been hypothesised that it illusions are a cultural thing. x

This illusion isn't even an illusion. its based on a theory that we percieve the world "top down" (that is we dont see things as they are but as we are used to seeing them). That is we are used to seeing the features of a face as convex (that is the nose sticks out) so our brain refuses to see it as concave (although it actually is), this is purley based on our previous knowledge about faces. its just the inside of a plastic mask. google Richard Gregory,

whats so special about a rotating mask?

creeeeeepy

yeah I know this one the ilusion happens when u loose concentration and u don't tell the difference its a nice ilusion

Dude Im High as shit, I could tell the difference, its all about memory and then you know like a lot of the things you didnt before, Peace and Love

The nose ring and popped out eyes on the hollow side gave it away. I could tell right off the bat by the way those two moved in relation to everything else...
