Optical illusion and illusion of logic

Optical illusion and illusion of logic

Our brain can be confused. The white cube on the left is concave. The white cube on the right is convex. This is an optical illusion.If you think these two configurations are all, then this is illusion of logic. They are not. The middle cube shows a third configuration. Can you find some of the other 5 configurations?HQ original: http://www.youtube.com/watch?v=WGfkNV6lIUYContact me at: [email protected]: x_YAMABIKO_x
