Sympathy is an app that gathers songs and creates unique and specifically tailored playlists to suit your mood. It uses facial recognition and scans the face to asses your mood and play music that corresponds to how you feel. Sympathy has many aesthetic compositions, satisfying gradients and other visuals that will vary according to your mood and the music. This prototype was done for a project in Graphic design major, Virginia Commonwealth University School of the Arts in Qatar.

I made this illusion based on the Tusi motion method, which takes his name from Nair al-Din Tusi, a Persian astronomer from the 13th century. The principle established by Tusi states that: If a circle with diameter A rotates on the inner boundary of a circle with diameter 2A, then a point on the circumference of the inner circle traces a straight line. As you can see, any ball in the inner circumference is following a perfect linear movement. This is created with 8 Containers where the balls move linear in a loop. The delay between balls must be always the same as the speed of the animation. An ease-in-out cubic-bezier(.4, 0, .6, 1) animation is required to get the circular shape.
