Here goes another test with the „sushi slider“. Now it works in a smoother way, without the pointer trembling so much and using all the magnet’s pot area(thanks Lucas!). The hand model in the video was also improved (thanks Yuchi!).
PS1: I believe that the reason the crazy bug occurs in the middle of the video its because I still need to put something in order to avoid the slider going besides magnet’s pot limits.
PS2: Next time I promisse to use an example that is not the upset girl. =P
