FaceYourFace vs Beautiful Trigonometry

Analyse and interpret facial expressions by mirroring face-halves. With great surprise and fun factor! Create a double-left and a double-right face from your face or that of your friends to show the differences between your left and your right half of your face. Which resulting face is more likeable and which is less likeable, left or right? Why do we hardly see the differences in everyday life when they are often crass? Are your body and your psyche in balance? Does the asymmetry make you more exciting, your face more interesting? Which half of your face is your public, action, controlled one and which side is your private, emotional side? Is it the same for all people? Easy to use tool! Saves a lot of work and time. Features: • List of people and faces • fast and good results with few finger movements • you can mirror both face-halves together (dependent) or separately (independent) • simple clipping of the result images • export and send the result images wherever you want • Websites with more informations and explanations about facial expressions and face-half mirroring or double face-halves Thanks for supporting us!
