1. Crazy Circle Illusion!
This is a simple but a goodie. Watch as the balls rotate in a circle ..but focus on one ball at a time and notice that it follows a straight line. Also, watch at the moment when there are only four balls moving, it forms a rotating square between the four balls. This is just another example of looking deeper into something so simple and discovering a hidden pattern.


2. Amazing Audio illusion
Listen to this video until the end, and when it stops, play it again to hear the difference, tune continue to "creep - up"... It will blow your mind!
